Saving Registers
In the interrupt sequence, only the contents of the flag register (FLG) and that of the program counter
(PC) are saved in the stack area.
First, the processor saves the 4 high-order bits of the program counter, and 4 high-order bits and 8 low-
order bits of the FLG register, 16 bits in total, in the stack area, then saves 16 low-order bits of the
program counter. Figure 1.12.6 shows the state of the stack as it was before the acceptance of the
interrupt request, and the state the stack after the acceptance of the interrupt request.
Save other necessary registers at the beginning of the interrupt routine using software. Using the
PUSHM instruction alone can save all the registers except the stack pointer (SP).
