(2) Interrupt mask flag register 0 (MK0)
Interrupt mask flags are used to enable and disable the corresponding maskable interrupts.
MK0 is set using a 1-bit or 8-bit memory manipulation instruction.
RESET input sets this register to FFH.

Cautions 1. When the watchdog timer is being used in watchdog timer mode 1 or 2, any attempt to
read the WDTMK flag results in an undefined value being detected.
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.
