Bit 0—Timer B Interrupt Request Flag (IRRTB)
Bit 0: IRRTB

1
Wakeup Interrupt Request Register (IWPR)
Note: * Only a write of 0 for flag clearing is possible.
IWPR is an 8-bit read/write register, in which the corresponding bit is set to 1 when pins WKP
WKP
automatically when an interrupt is accepted. It is necessary to write 0 to clear each flag.
Bits 7 to 0—Wakeup Interrupt Request Flags (WKPF7 to WKPF0)

pins WKP
5 (PMR5) and falling edge input is detected, the corresponding bit in the wakeup interrupt request
register (IWPR) is set to 1, requesting an interrupt. Wakeup interrupt requests can be disabled by
clearing the IENWP bit in IENR1 to 0. It is also possible to mask all interrupts by setting the CCR
I bit to 1.

Description
Clearing conditions:
When IRRTB = 1, it is cleared by writing 0
Setting conditions:
When the timer B counter value overflows (goes from H'FF to H'00)
Description
Clearing conditions:
When IWPFn = 1, it is cleared by writing 0 to IWPFn
Setting conditions:
IWPFn is set when pin WKP
