cc
contents of the Stack Pointer (SP) register pair is moved to the low order
eight bits of the Program Counter (PC). The SP is incremented and the byte
at the memory location specified by the new contents of the SP are moved
to the high order eight bits of the PC. The SP is incremented again. The
next Op Code following 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
instruction. If condition
and the program continues with the next sequential instruction. Condition
cc is programmed as one of eight status that correspond to condition bits in
the Flag Register (register F). These eight status are defined in the table
below, which also specifies the corresponding
object code.
