INTM0
MK0
The interrupt mask flag is used to enable and disable the corresponding maskable interrupts.
MK0 is set with a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets MK0 to FFH.
This register is used to set the valid edge of INTP0 and INTP1.
INTM0 is set with an 8-bit memory manipulation instruction.
Reset signal generation clears INTM0 to 00H.
