Bit 0: Asynchronous event counter interrupt request flag (IRREC)
Bit 0
IRREC
Description
0
Clearing conditions:
(initial value)
When IRREC = 1, it is cleared by writing 0
1
Setting conditions:
When ECH overflows in 16-bit counter mode, or ECH or ECL overflows
in 8-bit counter mode
6.
Wakeup Interrupt Request Register (IWPR)
IWPR is an 8-bit read/write register containing wakeup interrupt request flags. When one of pins
WKP
7
to
WKP
0
is designated for wakeup input and a rising or falling edge is input at that pin, the
corresponding flag in IWPR is set to 1. A flag is not cleared automatically when the corresponding
interrupt is accepted. Flags must be cleared by writing 0.
Bits 7 to 0: Wakeup interrupt request flags (IWPF7 to IWPF0)
Bit n
IWPFn
Description
0
Clearing conditions:
(initial value)
When IWPFn= 1, it is cleared by writing 0
1
Setting conditions:
When pin
WKP
n
is designated for wakeup input and a rising or falling edge is input
at that pin
