ME Power Failure Sensor
The IPMC evaluates the ME Power Failure Register to report power failures at the ME engine
domain. When a ME failure occurs, the red power failure LED (signal PWR_FAIL_) is blinking.
The error state is kept until ME wakes up (signal SLP_A_ becomes high). For more information,
see
For failing states and their coding, see
9.3.9
Payload Power Failure State Sensor
The IPMC evaluates the Payload Power Failure Register to report power failures at the payload
domain.
When a Payload Power failure occurs, the red power failure LED is switched ON (signal
PWR_FAIL_
is driven low).
