Interrupt mask flag registers 0, 1 (MK0, MK1)
The interrupt mask flag is used to enable and disable the corresponding maskable interrupts.
MK0 and MK1 are set with a 1-bit or 8-bit memory manipulation instruction.
Generation of reset signal sets MK0 and MK1 to FFH.
Caution Because P30, P31, P41, and P43 have an alternate function as external interrupt inputs,

After reset: FFH
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.
