Call the subroutine in page 2 : Calls the subroutine at address a in page 2.
Call the subroutine : Calls the subroutine at address a in page p.
Call the subroutine : Calls the subroutine at address (a6 a5 a4 A3 A2 A1 A0) determined by replacing the
low-order 4 bits of address a in page p with register A.
Returns from subroutine to the routine called the subroutine.
Returns from subroutine to the routine called the subroutine, and skips the next instruction at uncondition.
Transfers the contents of timer 1 to registers A and B.
Transfers the contents of registers A and B to timer 1.
Transfers the contents of register A to registers V1.
Skips the next instruction when the contents of T1F flag is “1.”
After skipping, clears (0) to T1F flag.
Transfers the contents of register A to register C.
Transfers the contents of register C to register A. In this case, port CARR output latch is cleared to “0.”
Transfers the contents of bit 3 (A3) of register A to port CARR output latch.
