SmartDesign MSS
Cortex™ -M3 Configuration
User Guide
Introduction
The SmartFusion Microcontroller Subsystem (MSS) contains an ARM Cortex-M3
microcontroller, a lowpower processor that features low gate count, low and
predictable interrupt latency, and low-cost debug. It is intended for deeply
embedded applications that require fast interrupt response features.
This document describes the ports that are available on the Cortex-M3 core in
the SmartDesign MSS Configurator.
For more information about the specific implementation of the Cortex-M3 in the
Actel SmartFusion device, please refer to the Actel SmartFusion
Microcontroller Subsystem User’s
Guide.
Configuration Options
There are no configuration options for the Cortex-M3 core in the SmartDesign MSS Configurator.
Port Description
| Port Name | Direction | PAD? | Description |
|---|---|---|---|
| RXEV | In | No | Causes the Cortex-M3 to wake up from a WFE ( wait for event ) |
instruction. The event
input, RXEV, is registered even when not waiting for an event, and so affects
the next
WFE.
TXEV| Out| No| Event transmitted as a result of a Cortex-M3 SEV ( send event )
instruction. This is a
single-cycle pulse equal to 1 FCLK period.
SLEEP| Out| No| This signal is asserted when the Cortex-M3 is in sleep now or
sleep-on-exit mode, and
indicates that the clock to the processor can be stopped.
DEEPSLEEP| Out| No| This signal is asserted when the Cortex-M3 is in sleep
now or sleep-on-exit mode when
the SLEEPDEEP bit of the System Control Register is set.
Note:
Non-PAD ports must be promoted manually to the top level from the MSS
configurator canvas to be available as the next level of hierarchy.
