(2) Interrupt mask flag registers (MK0L, MK0H, MK1L, MK1H, MK2L, MK2H)

Note
Cautions 1. Be sure to clear bits 6 and 7 of the IF2H register to 0 (except for
The interrupt mask flags are used to enable/disable the corresponding maskable interrupt servicing.
The MK0L, MK0H, MK1L, MK1H, MK2L, and MK2H registers can be set by a 1-bit or 8-bit memory manipulation
instruction. When the MK0L and MK0H registers, the MK1L and MK1H registers, and the MK2L and MK2H registers
are combined to form 16-bit registers MK0, MK1, and MK2, they can be set by a 16-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

after clearing the interrupt request flag. An interrupt request flag may be set by noise.
instruction (CLR1). When describing in C language, use a bit manipulation instruction such as
“IF0L.0 = 0;” or “_asm(“clr1 IF0L, 0”);” because the compiled assembler must be a 1-bit memory
manipulation instruction (CLR1).
If a program is described in C language using an 8-bit memory manipulation instruction such as
“IF0L &= 0xfe;” and compiled, it becomes the assembler of three instructions.
In this case, even if the request flag of the another bit of the same interrupt request flag register
(IF0L) is set to 1 at the timing between “mov a, IF0L” and “mov IF0L, a”, the flag is cleared to 0
at “mov IF0L, a”. Therefore, care must be exercised when using an 8-bit memory manipulation
instruction in C language.
