5.1.2 Software Interrupts
(1) Undefined-instruction interrupt
(2) Overflow interrupt
(3) BRK interrupt
(4) INT instruction interrupt
Software interrupts are generated by some instruction that generates an interrupt request when ex-
ecuted. Software interrupts are nonmaskable interrupts.
This interrupt occurs when the UND instruction is executed.
This interrupt occurs if the INTO instruction is executed when the O flag is 1.
The following lists the instructions that cause the O flag to change:
ABS, ADC, ADCF, ADD, CMP, DIV, DIVU, DIVX, NEG, RMPA, SBB, SHA, SUB
This interrupt occurs when the BRK instruction is executed.
This interrupt occurs when the INT instruction is executed after specifying a software interrupt number
from 0 to 63. Note that software interrupt numbers 0 to 31 are assigned to peripheral I/O interrupts. This
means that by executing the INT instruction, you can execute the same interrupt routine as used in
peripheral I/O interrupts.
The stack pointer used in INT instruction interrupt varies depending on the software interrupt number.
For software interrupt numbers 0 to 31, the U flag is saved when an interrupt occurs and the U flag is
cleared to 0 to choose the interrupt stack pointer (ISP) before executing the interrupt sequence. The
previous U flag before the interrupt occurred is restored when control returns from the interrupt routine.
For software interrupt numbers 32 to 63, such stack pointer switchover does not occur.
