Description

1: Power good

M_PG<x>_STAT

Power good status interrupt mask register

0: Not masked

1: Masked. No IRQ signal sent. Power good status register (PG <x>) is updated

TEMP_WARN

Asserted as long as the thermal warning threshold (TWARN) is reached

0: Junction temperature is below TWARN

1: Junction temperature is above TWARN

M_VR_HOT

Temperature warning status (TEMP_WARN) interrupt mask register

0: Not masked

1: Masked. No IRQ signal sent. Temperature warning status register (TEMP_WARN) is updated

System good. Asserted as long as the buck1 PG signal is high

0: Not system good

1: System good

It is possible to route interrupts to a GPIO by setting the bitfield GPIO<x>_MODE = 0xC on the relevant GPIO.

nIRQ’s behavior is shown in Figure 10 If GPIO_n_POL = 0, nIRQ will be high under normal operation, when

system-good status is high, and pulled low if an event listed in the Table 13 occurs.
