MULTI-ADDRESS JUMPING
Users can jump round multi-address by either JMP instruction or ADD M, A instruction (M = PCL) to activate
multi-address jumping function. If carry signal occurs after execution of ADD PCL, A, the carry signal will not affect
PCH register.
ꢃExample: If PC = 0323H (PCH = 03H、PCL = 23H)
; PC = 0323H

; PCL = PCL + ACC, the PCH cannot be changed.
; If ACC = 0, jump to A0POINT
; ACC = 1, jump to A1POINT
; ACC = 2, jump to A2POINT
; ACC = 3, jump to A3POINT
