An undefined instruction interrupt occurs when executing the UND instruction.
An overflow interrupt occurs when executing the INTO instruction with the O flag set to “1” (the opera-
tion 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
A BRK interrupt occurs when executing the BRK instruction.
An INT instruction interrupt occurs when executing the INT instruction. Software interrupt numbers 0
to 63 can be specified for the INT instruction. Because software interrupt numbers 4 to 31 are as-
signed 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
cleared 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 SP then selected is used.
