popped to Index Register IX. 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 IX the byte at the memory location corresponding
to the contents of SP; then SP is incremented and the contents of the
corresponding adjacent memory location are loaded to the high order
portion of IX. The SP is incremented again.
