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 4 to 31 are assigned to the
peripheral function interrupt. Therefore, the microcomputer 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.
