(1) Interrupt request flag registers (IF0L, IF0H, IF1L, IF1H, IF2L, IF2H)
The interrupt request flags are set to 1 when the corresponding interrupt request is generated or an instruction is
executed. They are cleared to 0 when an instruction is executed upon acknowledgment of an interrupt request or
upon reset signal generation.
When an interrupt is acknowledged, the interrupt request flag is automatically cleared and then the interrupt
routine is entered.
IF0L, IF0H, IF1L, IF1H, IF2L, and IF2H can be set by a 1-bit or 8-bit memory manipulation instruction. When
IF0L and IF0H, IF1L and IF1H, and IF2L and IF2H are combined to form 16-bit registers IF0, IF1, and IF2, they
can be set by a 16-bit memory manipulation instruction.
Reset signal generation clears these registers to 00H.
Remark If an instruction that writes data to this register is executed, the number of instruction execution clocks
