(1) Interrupt request flag register 0 (IF0)
An interrupt request flag is set (1) when the corresponding interrupt request is generated, or when an
instruction is executed. It is cleared (0) when the interrupt request is acknowledged, when the RESET signal
is input, or when an instruction is executed.
IF0 is set using a 1-bit or 8-bit memory manipulation instruction.
RESET input sets this register to 00H.

No interrupt request signal generated
1
An interrupt request signal is generated and an interrupt request made
Cautions 1. The WDTIF flag can be read/written only when the watchdog timer is being used as an
interval timer. It must be cleared to 0 if the watchdog timer is used in watchdog timer
mode 1 or 2.
2. Because P61 functions alternately as an external interrupt, when the output level
changes after the output mode of the port function is specified, the interrupt request flag
will be inadvertently set. Therefore, be sure to preset the interrupt mask flag (PMK0)
before using the port in output mode.
