Description: The top two bytes of the external memory LIFO (last-in, first-out) Stack
Condition Bits Affected: None

qq
are popped to register pair qq. The Stack Pointer (SP) register pair holds
the 16-bit address of the current top of the Stack. This instruction first
loads to the low order portion of qq, the byte at memory location
corresponding to the contents of SP; then SP is incriminated and the
contents of the corresponding adjacent memory location are loaded to the
high order portion of qq and the SP is now incriminated again. The
operand qq identifies register pair BC, DE, HL, or AF, assembled as
follows in the object code:
