Table 14: Interrupt Registers Except for Power Good Status

Description

E_<name>

Read-only interrupt event register

0: No interrupt

1: Interrupt occurred

Cleared after being written to I2C. Set until IRQ is removed.

M_<name>

Interrupt mask register

0: Not masked

1: Masked. No IRQ signal sent. Event register (E_<name>) is updated.

Table 15: Interrupt Registers for Power Good and Temp Warning Status

Description

PG<x>

Buck<x> power good status. Asserted as long as the buck<x> output voltage is in range

(under-voltage threshold < buck output voltage < over-voltage threshold)

0: Not power good

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
