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

Table 5-44

.

For failing states and their coding, see

Table 5-45

.

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).
