2.2.60 EXTERNAL INTERRUPT CONTROL REGISTERS

External Interrupt consists of 32 bits. EXT_INT[31:0] are used for wake-up source in Power down mode. In idle
mode, all interrupts can be wake-up source; the other groups of external interrupts also can be the wake-up
sources.
EXT_INT[0] can be used PS_HOLD_CONTROL. For more information on PS_HOLD_CONTROL Register, refer
to Chapter 02.04. PMU.
The table below lists the external interrupt control registers.
