7.4.9.2 Configured as Sequencing Debug Pin

When the pin is asserted, device does not alert PMBUS_Alert pin, not response for faults, log faults defined in the Table 7-6. The rail sequence on/off dependency conditions are ignored, as soon as the sequence on/off timeout is expired, the rails will be sequenced on or off accordingly regardless of the timeout action, if the sequence on/off timeout value is set to 0, the rails is sequenced on or off immediately. The fault pins do not pull the fault bus low. The LGPOs affected by these events should be back to it original states.

Table 7-6 List of Events Affected by Debug Mode
EventsDescription
VOUT_OV_FAULTVoltage Rail is over OV fault threshold
VOUT_OV_WARNINGVoltage Rail is over OV warning threshold
VOUT_UV_FAULTVoltage Rail is under UV fault threshold
VOUT_UV_WARNINGVoltage Rail is under UV warning threshold
TON_MAXVoltage Rail fails to reach power good threshold in predefined period.
TOFF_MAX WarningVoltage rail fails to reach power not good threshold in predefined period
IOUT_OC_FAULTCurrent Rail is over OC fault threshold
IOUT_OC_WARNINGCurrent Rail is under OC warning threshold
IOUT_UCCurrent Rail is under UC fault threshold
OT_FAULTTemperature Rail has over OT fault threshold
OT_WARNINGTemperature Rail has over OT warning threshold
All GPI de-assertedNo logging and fault response, but the function of the GPI is not ignored.
SYSTEM_WATCHDOG_TIMEOUTSystem watch timeout
RESEQUENCE_ERRORRail fails to resequence
SEQ_ON_TIMEOUTRail fails to meeting sequence on dependency in predefined period
SEQ_OFF_TIMEOUTRail fails to meeting sequence on dependency in predefined period
SLAVE_FAULTRail is shut down due to that its master has fault
