qq
LIFO (last-in, first-out) Stack. The Stack Pointer (SP) register pair holds the
16-bit address of the current top of the Stack. This instruction first
decrements SP and loads the high order byte of register pair qq to the
memory address specified by the SP. The SP is decremented again and
loads the low order byte of qq to the memory location corresponding to this
new address in the SP. The operand qq identifies register pair BC, DE, HL,
or AF, assembled as follows in the object code:
