MULTI-ADDRESS JUMPING

Users can jump around the multi-address by either JMP instruction or ADD M, A instruction (M = PCL) to activate

multi-address jumping function. Program Counter supports “ADD M,A”, ”ADC M,A” and “B0ADD M,A” instructions

for carry to PCH when PCL overflow automatically. For jump table or others applications, users can calculate PC value

by the three instructions and don’t care PCL overflow problem.

Note: PCH only support PC up counting result and doesn’t support PC down counting. When PCL is

carry after PCL+ACC, PCH adds one automatically. If PCL borrow after PCL–ACC, PCH keeps value and

not change.

Example: If PC = 0323H

(PCH = 03H, PCL = 23H)

; PC = 0323H

MOV

A, #28H

B0MOV

PCL, A

; Jump to address 0328H

…

; PC = 0328H

MOV

A, #00H

B0MOV

PCL, A

; Jump to address 0300H

…

Example: If PC = 0323H

(PCH = 03H, PCL = 23H)

; PC = 0323H

B0ADD

PCL, A

; PCL = PCL + ACC, the PCH cannot be changed.

JMP

A0POINT

; If ACC = 0, jump to A0POINT

JMP

A1POINT

; ACC = 1, jump to A1POINT

JMP

A2POINT

; ACC = 2, jump to A2POINT

JMP

A3POINT

; ACC = 3, jump to A3POINT
