(1) Interrupt request flag register 0 (IF0)
An interrupt request flag is set to 1 when the corresponding interrupt request is issued, or when the instruction is
executed. It is cleared to 0 by executing an instruction when the interrupt request is acknowledged or when a
reset signal is input.
IF0 is set with a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears IF0 to 00H.

Caution Because P21 and P32 have an alternate function as external interrupt inputs, when the
output level is changed by specifying the output mode of the port function, an interrupt
request flag is set. Therefore, the interrupt mask flag should be set to 1 before using the
output mode.
