SmartFusion2 MSS Configurator
User Guide
Introduction
The MSS Component Configurator presents you with a graphical block diagram of the SmartFusion2 Micro controller Subsystem. You can enable/disable and configure each MSS sub-block as per your application requirements (Figure 1).
Peripherals
Enabling/Disabling MSS Sub-blocks
Certain peripherals in the MSS can be enabled or disabled. This is indicated
graphically by the checkbox in the lower right corner of the instance item in
the Canvas, as shown in Figure 1-1.
Click the checkbox icon to enable or disable the sub-block.
You can also use the shortcut (right-click) menu to enable or disable a block.
To do so, right-click the block and choose Disable.
Why would I disable or enable a sub-block?
- Disabling a sub-block causes it to be held in reset when the Micro controller Subsystem is powered up. This minimizes any activity that may occur in the sub-block after startup and reduces power consumption.
- In the case of digital peripherals such as USB, Ethernet MAC, MMUART, I2C, SPI, CAN and GPIO it is important to disable peripherals that are not used by the application as they share chip level general purpose I/O resources with other peripherals as well as the FPGA fabric. Leaving a peripheral enabled may prevent you from using other peripherals and lower the total number of general purpose I/Os available to the FPGA fabric.
Configuring Sub-blocks
MSS peripherals that have configurable options have a wrench icon in the lower
right corner of the instance item in the Canvas, as shown in Figure 1-2.
Click the wrench icon or double-click the instance to configure the
peripheral.
You can also use the shortcut (right-click) menu to configure the sub-block. To do so, right-click the sunblock and choose Configure.
MSS Configuration Guidelines
Although the MSS configurator allows you to configure all sub-blocks out of
order, Microsemi recommends that you configure the various sub-blocks in a
particular order as the configuration of some sub-blocks depends on others.
Configure the MSS sub-blocks in the following order:
-
External Memory Configuration (MDDR sub-block)
-
Fabric Interface Controller (FIC32_0 and FIC32_1 sub-blocks)
-
MSS digital peripherals in the following order to minimize I/O sharing conflicts:
– Disable all peripherals that are not being used
– Configure USB and Ethernet MAC
– Configure MMUART, I2C, SPI and CAN peripherals
– Configure GPIO’s -
Clocks (CCC sub-block)
-
Resets (RESET sub-blocks)
-
All other blocks
For example, re-configuring the Fabric Controller Interfaces (FIC32) impacts how the MSS clocks (CCC) are configured:
- Using the CAN will require that the MSS clock (M3_CLK) be a multiple of 8 MHz
- Using the USB requires that the MSS clock (M3_CLK) be greater than 30.1 MHz
- Configuring the GPIO’s first may prevent you from using an entire digital peripheral
Refer to the Configuring the MSS Clock Sub-system document for more details
about MSS clock configuration requirements.
For more information on configuring the MSS Sub-blocks, see their
documentation.
