Remark 1 clock: 1/f
Remark 1 clock: 1/f
A software interrupt acknowledge is acknowledged by BRK instruction execution.
If a software interrupt request is acknowledged, the contents are saved into the stacks in the order of the program
Restoring from a software interrupt is possible by using the RETB instruction.
Caution Do not use the RETI instruction for restoring from the software interrupt.
