Each ESM module implements the following features:
- Up to 1024 error event inputs
- Implemented in groups of 32 events
- Level or Pulse inputs (Pulse inputs are triple redundant)
- Selectable low and high priority interrupt error pin prioritization of each error event
- Error pin to signal severe device failure
- Support of level or PWM modes
- Configurable timebase for error signal
- Error forcing capability
- Internal redundant flops on critical fields
