ISR_0 (AMS) Register Description

Register NameISR_0
Offset Address0x0000000010
Absolute Address 0x00FFA50010 (AMS_CTRL)
Width32
TypewtcReadable, write a 1 to clear
Reset Value0x00000000
DescriptionAlarm Interrupt Status and Clear, Reg 0. PS and PL.

The first half of this register are alarms for the PS. The second half are for the PL. Bits are set by hardware and cleared by PMU software by writing a 1 to a bit. READ: 0: no alarm. 1: alarm latched. WRITE: 0: no effect. 1: clear the bit. The threshold and sequence control registers are described in the PSSYSMON and PLSYSMON register sets.
