14.3.2 Interrupt mask flag registers (MK0L, MK0H, MK1L)
The interrupt mask flags are used to enable/disable the corresponding maskable interrupt servicing.
The MK0L, MK0H, and MK1L registers can be set by a 1-bit or 8-bit memory manipulation instruction. Reset signal
generation sets these registers to FFH.
Remark If an instruction that writes data to this register is executed, the number of instruction execution clocks
increases by 2 clocks.
