(2) Interrupt mask flag registers (MK0L, MK0H, MK1L, MK1H)
398
Caution Be sure to set bits 1, 2, 4 to 7 of MK1L and bits 0 to 7 of MK1H to 1.
The interrupt mask flags are used to enable/disable the corresponding maskable interrupt servicing.
MK0L, MK0H, MK1L, and MK1H are set by a 1-bit or 8-bit memory manipulation instruction. When MK0L and
MK0H, and MK1L and MK1H are combined to form 16-bit registers MK0 and MK1, they are set by a 16-bit
memory manipulation instruction.
Reset signal generation sets these registers to FFH.
