9.3.8 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).
