A software interrupt is generated when an instruction is executed. The software interrupts are non-maskable
interrupts.
The undefined instruction interrupt is generated when the UND instruction is executed.
The overflow interrupt is generated when the O flag is set to 1 (arithmetic operation overflow) and the INTO
instruction is executed. Instructions to set the O flag are:
ABS, ADC, ADCF, ADD, CMP, DIV, DIVU, DIVX, NEG, RMPA, SBB, SHA, SUB
A BRK interrupt is generated when the BRK instruction is executed.
An INT instruction interrupt is generated when the INT instruction is executed. The INT instruction can select
software interrupt numbers 0 to 63. Software interrupt numbers 3 to 31 are assigned to the peripheral function
interrupt. Therefore, the MCU executes the same interrupt routine when the INT instruction is executed as
when a peripheral function interrupt is generated. In software interrupt numbers 0 to 31, the U flag is saved to
the stack during instruction execution and set the U flag to 0 (ISP selected) before executing an interrupt
sequence. The U flag is restored from the stack when returning from the interrupt routine. In software interrupt
numbers 32 to 63, the U flag does not change state during instruction execution, and the selected SP is used.
