Skip condition
Detailed description
–
– 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.
Skip at uncondition – Returns from subroutine to the routine called the subroutine, and skips the next instruction at uncondition.
–
– At timer 1 stop (V10 = 0), transfers the contents of register A and register B to timer 1 and reload
register R1.
At timer 1 operating (V10 = 1), transfers the contents of register A and register B to reload register R1.
–
– Transfers the contents of timer 1 to registers A and B.
–
(T1F) = 1
–
– Transfers the contents of register A to registers V1.
– _{Clears T1F flag and skips the next instruction when the contents of T1F flag is “1.”}
– ^{Transfers the contents of register A and register B to timer 2 and reload register R2L.}
