Description
Software Standby Release IRQ Setting
These bits select the IRQn pins used to recover from
the software standby state.
0: IRQn requests are not sampled in the software
1: When IRQn request occurs in the software standby
standby state (Initial value when n = 7 to 3).
state, the chip recovers from the software standby
state after the elapse of the oscillation settling time
(Initial value when n = 2 to 0).
When the interrupt source selected by ISCR
occurs
Cleared after reading condition1, when written as
0
When interrupt exception handling is executed
when low-level detection is set and IRQn input is
high
When IRQn interrupt exception handling is
executed while detecting the falling edge, rising
edge, or both
