INTERFACE

Global Coexistence Interface

• The 03ACCY0002 supports the proprietary Cypress Global Coexistence Interface (GCI) which is a two-wire interface.
• The following key features are associated with the interface:
• Enhanced coexistence data can be exchanged over GCI_SECI_IN and GCI_SECI_OUT a two-wire interface, one serial input (GCI_SECI_IN), and one serial output (GCI_SECI_OUT).
• Both pins are controlled by the configuration file that is stored in EEPROM from the host.
• It supports generic UART communication between WLAN and Bluetooth devices.
• To conserve power, it is disabled when inactive.
• It supports automatic resynchronization upon waking from sleep mode.
• It supports a baud rate of up to 4 Mbps.

Table 8: BT GCI two-wire coexistence

USB Interface

• 03ACCY0002 has a full-speed (12 Mbps) USB interface for communicating with other compatible digital devices.
• The USB interface on the 03ACCY0002 acts as a USB peripheral, responding to requests from a master host controller.
• 03ACCY0002 supports the Universal Serial Bus Specification (USB v2.0 Specification) and USB Battery Charging Specification, available from http://www.usb.org.
• For more information on how to integrate the USB interface on 03ACCY0002d see the following section: USB Dongle Design Example Using 03ACCY0002.

The following USB interface features are supported:

• USB Protocol, revision 2.0, full-speed compliant with LPM support (up to 12 Mbps)
• Bluetooth HCI
• Integrated detach resistor
• USB termination when an interface is not in use
• Internal modules, certification, and non-specification-compliant operation

PCM Interface

• The 03ACCY0002 supports two independent PCM interfaces that share the pins with I2S interfaces. The PCM interface on the 03ACCY0002 can connect to linear PCM Codec devices in master or slave mode. In master mode, the 03ACCY0002 generates the PCM_CLK and PCM_SYNC signals; in slave mode, these signals are provided by another master on the PCM interface and are inputs to the 03ACCY0002.
• The configuration of the PCM interface may be adjusted by the host through the use of vendor-specific HCI commands.

Slot Mapping

• The 03ACCY0002 supports up to three simultaneous full-duplex SCO or eSCO channels through the PCM interface. These three channels are time-multiplexed onto the single PCM interface by using a time-slotting scheme where the 8 kHz or 16 kHz audio sample interval is divided into as many as 16 slots. The number of slots is dependent on the selected interface rate of 128 kHz, 512 kHz, or 1024 kHz. The corresponding number of slots for these interface rates is 1, 2, 4, 8, and 16, respectively. Transmit and receive PCM data from an SCO channel is always mapped to the same slot. The PCM data output driver tri-states its output on unused slots to allow other devices to share the same PCM interface signals.
• The data output driver tristates its output after the falling edge of the PCM clock during the last bit of the slot.

Frame Synchronization

• The 03ACCY0002 supports both short- and long-frame synchronization in both master and slave modes. In short-frame synchronization mode, the frame synchronization signals an active-high pulse at the audio frame rate that is a single-bit period in width and is synchronized to the rising edge of the bit clock. The PCM slave looks for a high on the falling edge of the bit clock and expects the first bit of the first slot to start at the next rising edge of the clock.
• Figure 2 and Table 9 show the PCM Timing Diagram and Specifications for the master mode of short-frame.

• In long-frame synchronization mode, the frame synchronization signal is again an active-high pulse at the audio frame rate; however, the duration is three-bit periods and the pulse starts coincident with the first bit of the first slot.
• Figure 4 and Table 11 show the PCM Timing Diagram and Specifications for the master mode of long-frame.

Data Formatting

• The 03ACCY0002 may be configured to generate and accept several different data formats. For conventional narrowband speech mode, the 03ACCY0002 uses 13 of the 16 bits in each PCM frame.
• The location and order of these 13 bits can be configured to support various data formats on the PCM interface. The remaining three bits are ignored on the input and may be filled with 0s, 1s, a sign bit, or a programmed value on the output.
• The default format is 13-bit 2’s complement data, left justified, and clocked MSB first.

Wideband Speech Support

When the host encodes Wideband Speech (WBS) packets in transparent mode, the encoded packets are transferred over the PCM bus for an eSCO voice connection. In this mode, the PCM bus is typically configured in master mode for a 4-kHz sync rate with 16-bit samples, resulting in a 64 Kbps bit rate. The 03ACCY0002-Sx also supports slave transparent mode using a proprietary rate- matching scheme. In SBC-code mode, linear 16-bit data at 16 kHz (256 Kbps rate) is transferred over the PCM bus.

Multiplexed Bluetooth Over PCM

Bluetooth supports multiple audio streams within the Bluetooth channel and both 16 kHz and 8 kHz streams can be multiplexed. This mode of operation is only supported when the Bluetooth host is the master. Figure 6 shows the operation of the multiplexed transport with three simultaneous SCO connections. To accommodate additional SCO channels, the transport clock speed is increased. To change between modes of operation, the transport must be halted and restarted in the new configuration.

Burst PCM Mode

• In this mode of operation, the PCM bus runs at a significantly higher rate of operation to allow the host to duty cycle its operation and save current.
• In this mode of operation, the PCM bus can operate at a rate of up to 24 MHz.
• This mode of operation is initiated with an HCI command from the host.
• Figure 7 and Table 13 show the PCM Burst mode timing diagram and specifications for the receive-only mode of short-frame sync.

I2S Interface

The 03ACCY0002-Sx supports two independent I2S digital audio ports. The I2S interface supports both master and slave modes.

The I2S signals are:

• I2S clock: I2S SCK
• I2S Word   Select: I2S WS
• I2S Data Out: I2S SDO
• I2S Data In  I2S SDI
• I2S SCK and I2S WS become outputs in master mode and inputs in slave mode, while I2S SDO always stays as an output.
• The channel word length is 16 bits and the data is justified so that the MSB of the left-channel data is aligned with the MSB of the I2S bus, per the I2S specification.
• The MSB of each data word is transmitted a one-bit clock cycle after the I2S WS transition, synchronous with the falling edge of the bit clock.
• Left-channel data is transmitted when I2S WS is low, and right-channel data is transmitted when I2S WS is high.
• Data bits sent by the 03ACCY0002 are synchronized with the falling edge of I2S_SCK and should be sampled by the receiver on the rising edge of I2S_SSCK.

The clock rate in master mode is either of the following:

• 48 kHz x 32 bits per frame = 1.536 MHz
• 48 kHz x 50 bits per frame = 2.400 MHz
• The master clock is generated from the input reference clock using a N/M clock divider. In the slave mode, any clock rate is supported to a maximum of 3.072 MHz.

• Timing values specified in Table 15 are relative to high and low threshold levels.
