Software interrupts are non-maskable. A software interrupt is generated by executing an instruction.
There are five types of software interrupts as follows:
(1) Undefined Instruction Interrupt
(2) Overflow Interrupt
(3) BRK Instruction Interrupt
(4) BRK2 Instruction Interrupt
(5) INT Instruction Interrupt
This interrupt occurs when the UND instruction is executed.
This interrupt occurs when the INTO instruction is executed while the O flag is 1. The following
instructions may change the O flag to 1, depending on the operation result:
ABS, ADC, ADCF, ADD, ADDF, ADSF, CMP, CMPF, CNVIF, DIV, DIVF, DIVU, DIVX, EDIV, EDIVU,
EDIVX, MUL, MULF, MULU, MULX, NEG, RMPA, ROUND, SBB, SCMPU, SHA, SUB, SUBF, SUNTIL,
and SWHILE
This interrupt occurs when the BRK instruction is executed.
This interrupt occurs when the BRK2 instruction is executed.
This interrupt is only meant for use with the development support tool, and users are not allowed to use
it.
This interrupt occurs when the INT instruction is executed with a selected software interrupt number
from 0 to 255. Numbers 0 to 127 are designated for peripheral interrupts. That is, the INT instruction
with a number from 0 to 127 has the same interrupt handler as that for the peripheral interrupt.
The stack pointer (SP), which contains two types, is specified by the stack pointer select flag (U flag).
For numbers 0 to 127, when an interrupt request is accepted, the U flag is saved to select the interrupt
stack pointer (ISP) before the interrupt sequence is executed. The saved data of the U flag is restored
upon returning from the interrupt handler. For numbers 128 to 255, the stack pointer used before the
interrupt request acceptance remains unchanged for the interrupt sequence.
