14. Interrupts

14.7.5

Saving Registers

In the interrupt sequence, the FLG register and PC are saved on the stack.
At this time, the 4 upper bits of the PC and the 4 upper (IPL) and 8 lower bits in the FLG register, 16 bits
in total, are saved on the stack first. Next, the 16 lower bits of the PC are saved. Figure 14.5 shows the
Stack Status Before and After Acceptance of Interrupt Request.
The other necessary registers must be saved by a program at the beginning of the interrupt routine.
Use the PUSHM instruction, and all registers except SP can be saved with a single instruction.

Figure 14.5

Stack Status Before and After Acceptance of Interrupt Request

The register save operation carried out in the interrupt sequence is dependent on whether the SP

the time of acceptance of an interrupt request, is even or odd. If the SP

is even, the FLG register and

the PC are saved 16 bits at a time. If odd, they are saved in two steps, 8 bits at a time. Figure 14.6
shows the Register Save Operation.

Note:
1.

When an INT instruction with software numbers 32 to 63 has been executed, it is the SP indicated
by the U flag. Otherwise, it is the ISP.
