Datasheet DA9130-A (Dialog Semiconductor) - 22

DA9130-A High-Performance, 10 A, Dual-Phase DC-DC Converter Table 14: Interrupt Registers Except for Power Good Status Register 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 Register 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 I2C
