Like the other aspects of the low-end PIC microcontroller architecture compared to the mid-range architecture, the smaller address size affects the way that execution change operates. The changes that you will have to keep in mind when you are creating low-end applications are the smaller page size, the difference in operation between the goto and call instructions, and the lack of a return instruction. None of these differences will prevent you from being able to port your applications between the two architectures, they are just a few things to watch for when you do it. For the call and goto instructions as well as those in which the contents of PCL are modi ed, the PA0 to PA2 bits of the STATUS register are used as the high order address bits of the actual jump address within a speci ed bank. These bits, while similar in operation to the PCLATH bits, require a slightly different approach because they are part of the STATUS register. In the mid-range devices, the two instructions:

are all that are required to set up the high order address bits for the goto or call instructions because the bits are organized to allow a direct transfer of the address to the PCLATH bits. This is not possible in the PA0 to PA2 bits in the STATUS register; instead, I recommend that you use the conditional assembly statements I introduced earlier in the chapter for updating the PA0 to PA1 bits. To do this, remember that PA0 is bit 9 of the address while PA2 is bit 11:

if ((NewAddress & 0x200) != 0) ; Only 1024 instructions available bsf STATUS, PA0 else bcf STATUS, PA0 endif goto (NewAddress & 0x1FF) | ($ & 0x200) ReturnAddress: goto $ org 0x234 NewAddress: if ((ReturnAddress & 0x200) != 0) bsf STATUS, PA0 else bcf STATUS, PA0 endif goto (ReturnAddress & 0x1FF) | ($ & 0x200)
In this program, the modi cations to the address in the goto statements are the same ones as would be done in a mid-range device. The number of bits available for addressing a page in the low-end PIC microcontroller s goto instruction is 9, which makes the size of the page 512 instructions. There is a problem with the call instruction because it has only 8 bits available for the offset of the start of the subroutine within the page and the 9th bit is always assumed to be reset. This means that a call instruction (as well as a write to PCL, which will be discussed in the next section) will only be able to access the rst 256 instructions of a lowend device page. If you attempt to call an address in the second 256 instructions of the page, the MPASM assembler will return an error. The solution to the problem should be obvious: never put a subroutine in the second 256 addresses of a low-end page. Unfortunately, this is not always possible, so the solution that normally used is to put a label with a goto in the rst 256 instructions of the page to the actual subroutine code. This allows the body of the subroutine to be in the second half of the page while not having any errors agged. When calling a subroutine in another page, always remember to restore the PA# bits upon return. To do this, check the page of the current address (using the $ directive) as shown below:
if ((CallAddress & 0x200) != 0) ; Required if Program Memory >= 1024 bsf STATUS, PA0 else bcf STATUS, PA0 endif
