249 / 452 page  Glossary S12CPUV2 Reference Manual, Rev. 4.0 Freescale Semiconductor 249 Operation: (SP) – $0002 ⇒ SP (A : B) ⇒ M(SP) :M(SP+1) Description: Stacks the content of double accumulator D. The stack pointer is decremented by two, then the contents of accumulators A and B are stored at the location to which the SP points. After PSHD executes, the SP points to the stacked value of accumulator A. This stacking order is the opposite of the order in which A and B are stacked when an interrupt is recognized. The interrupt stacking order is backward-compatible with the M6800, which had no 16-bit accumulator. Push instructions are commonly used to save the contents of one or more CPU registers at the start of a subroutine. Complementary pull instructions can be used to restore the saved CPU registers just before returning from the subroutine.
