The following points highlights the main
features of the Error Signaling Module Subsystem :
- ESM Subsystem consists of
three ESM CPU Instances (one for each CPU), a single System ESM (SYS ESM)
for Error Pin Output and Monitoring, and an additional Safety Aggregator
(ESM Register Parity Error Aggregator) Instance for Register Parity Error
Aggregation for all ESM instances (ESM CPU and System ESM).
- Supports up to 256 error
event inputs: Error events from Error Aggregator and System level fault
event sources are mapped to ESM subsystem and applied to all ESM instances
(Refer to Section 7.3.1 for more details)
- Divided in groups of
32 error events (Total 8 Groups)
- Selectable Low and High
Priority Interrupt prioritization of each error event for each ESM CPU
instance
- Critical Priority and High
Priority Watchdog Interrupt outputs for each ESM CPU instance
- System ESM Instance to signal
severe device failure produces an Error Pin Output in addition to set of
interrupt outputs
- Supports of level or
PWM modes for error pin output
- Error Pin
Monitoring
- Configurable timebase for
error pin signal output
- Error forcing capability
- Parity Detection and
Commit/Lock for MMRs
