11.1.6.7 Saving a Register
In the interrupt sequence, the FLG register and PC are saved to the stack.
After 4 high-order bits in the PC and 4 high-order (IPL) and 8 low-order bits in the FLG register,
extended to 16 bits, are saved to the stack, the 16 low-order bits in the PC are saved. Figure 11.7
shows the Stack State Before and After Acknowledgement of Interrupt Request.
The other necessary registers are saved by a program at the beginning of the interrupt routine. The
PUSHM instruction can save several registers in the register bank being currently used
(1)
with 1
instruction.
NOTES:
1. Selectable from the R0, R1, R2, R3, A0, A1, SB and FB registers.
Figure 11.7 Stack State Before and After Acknowledgement of Interrupt Request
The register saving operation which is performed in the interrupt sequence is saved in 8 bits every 4
steps. Figure 11.8 shows the Operation of Saving Register.
