(1) Interrupt request flag registers (IF0L, IF0H, IF1L, IF1H)
262
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 input.
When an interrupt is acknowledged, the interrupt request flag is automatically cleared and then the interrupt
routine is entered.
IF0L, IF0H, IF1L, and IF1H are set by a 1-bit or 8-bit memory manipulation instruction. When IF0L and IF0H, and
IF1L and IF1H are combined to form 16-bit registers IF0 and IF1, they are set by a 16-bit memory manipulation
instruction.
RESET input clears these registers to 00H.
