pCL ← (sp), pCH ← (sp+1)
RET
Pointer (SP) register pair is moved to the low order eight bits of the
Program Counter (PC). The SP is now incremented and the byte at the
memory location specified by the new contents of this instruction is fetched
from the memory location specified by the PC. This instruction is normally
used to return to the main line program at the completion of a routine
entered by a CALL instruction.
If the contents of the Program Counter are
Pointer are
