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, ADDX, CMP, CMPX, DIV, DIVU, DIVX, NEG, RMPA, SBB, SCMPU, SHA, SUB,
SUBX
This interrupt occurs when the BRK instruction is executed.
This interrupt occurs when the BRK2 instruction is executed. This interrupt is used exclusively for
debugger purposes. You normally do not need to use this interrupt.
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 54 and 57 are assigned to peripheral I/O inter-
rupts. 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.
However, in peripheral I/O interrupts, the U flag is saved when an interrupt occurs and the U flag is
cleared to 0 to choose ISP.
Therefore movement of U flag is different by peripheral I/O interrupt or INT instruction in software interrupt
number 32 to 54 and 57.
