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)
