10. Interrupt

Under development

This document is under development and its contents are subject to change.

10.2 Software Interrupts

A software interrupt occurs when executing certain instructions. Software interrupts are non-maskable

interrupts.

10.2.1 Undefined Instruction Interrupt

An undefined instruction interrupt occurs when executing the UND instruction.

10.2.2 Overflow Interrupt

An overflow interrupt occurs when executing the INTO instruction with the O flag in the FLG register set to

“1” (the operation resulted in an overflow). The following are instructions whose O flag changes by arithmetic:

ABS, ADC, ADCF, ADD, CMP, DIV, DIVU, DIVX, NEG, RMPA, SBB, SHA, SUB

10.2.3 BRK Interrupt

A BRK interrupt occurs when executing the BRK instruction.

10.2.4 INT Instruction Interrupt

An INT instruction interrupt occurs when executing the INT instruction. Software interrupt Nos. 0 to 63 can

be specified for the INT instruction. Because software interrupt Nos. 1 to 31 are assigned to peripheral

function interrupts, the same interrupt routine as for peripheral function interrupts can be executed by

executing the INT instruction.

In software interrupt Nos. 0 to 31, the U flag is saved to the stack during instruction execution and is set

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 Nos. 32 to 63, the U flag does not change state

during instruction execution, and the SP then selected is used.
