Interrupt Sequence
If IRQ
××
flag is set to “1” when IP
××
flag is “1”, interrupt processing is started after the instruction cycle of the instruction
executed when IRQ
××
flag was set has ended. Since the MOVT instruction, EI instruction, and the instruction which
matches the condition to skip use two instruction cycles, the interrupt enabled while this instruction is executed is
processed after the second instruction cycle is over.
If IP
××
flag is “0”, the interrupt processing is not performed even if IRQ
××
flag is set, until IP
××
flag is set.
If two or more interrupts are enabled simultaneously, the interrupts are processed starting from the one with the highest
priority. The interrupt with the lower priority is kept pending until the processing of the interrupt with the higher priority is
finished.
7.3.1
Operations when interrupt is accepted
When an interrupt has been accepted, the CPU performs processing in the following sequence:
Clears IRQ corresponding to
INTE flag and accepted interrupt
Decrements value of stack pointer by 1
(SP – 1)
Saves contents of program counter to
stack addressed by stack pointer
Loads vector address to program counter
Save contents of PSWORD to interrupt stack register
One instruction cycle is required to perform the above processing.
