EM78P510N  
8-Bit Microcontrollers  
"CALL" instruction loads the low 10 bits of the PC and PC+1, and then push into the  
stack.  
"RET'' ("RETL k", "RETI") instruction loads the program counter with the contents at the  
top of stack.  
"MOV R2, A" allows the loading of an address from the A register to the PC, and  
contents of the ninth and tenth bits don't change.  
"ADD R2, A" allows a relative address be added to the current PC, and contents of the  
ninth and tenth bits don't change.  
The most significant bit (A10~A11) will be loaded with the contents of Bit PS0~PS2 in  
the status register (R6) upon the execution of a "JMP'', "CALL'' instruction.  
Figure 6-2 Program Counter Organization  
User can use Long jump (LJMP) or long call (LCALL) instructions to program user's  
code. And the program page is maintained by ELAN's compiler. It will change user's  
program by inserting instructions within the program.
