Description: The contents of the Index Register IX are pushed to the external memory
Condition Bits Affected: None
Example:

PUSH
IX
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 IX to the memory address
specified by SP; then decrements SP again and loads the low order byte to
the memory location corresponding to this new address in SP.
