In an earlier version of MPLAB IDE, this message was not produced, and the assembler automatically inserted the retlw 0 instruction. This caused me several hours of confusion one night trying to gure out why code that ran ne in a mid-range PIC microcontroller wouldn t work in a low-end device. To avoid this problem, you may wish to always return values in a subroutine in a common variable rather than in the w register or use the STATUS ags to return pass/fail or other binary information. No interrupts in low-end PIC microcontrollers changes the way inputs and hardware events are monitored. Instead of waiting for an event, your code will have to poll for the event. If a signal waited for is very short, you may miss it. In Appendix G, I have a small snippet of code that will set up TMR0 of PIC microcontrollers to over ow when a signal is received. This will allow you to use the TMR0 hardware in the PIC microcontroller to indicate if a pulse has been received or a line has changed state without having to continually poll it. The last difference, the lack of bank select bits, will be the biggest issue you have in porting mid-range applications to low-end devices. The most obvious problem will be the need to convert all the bank switch writes to the OPTION_REG and the TRIS registers to the single-instruction equivalents, but there is a larger problem you should be aware of. In low-end devices, a register bank uses only 5 bits for addressing (in high-end devices, 7 address bits for each address are used). This only gives a maximum of 32 registers per bank. There can be up to four banks, each with shared INDF, TMR0, PCL, STATUS, FSR, PORTA, PORTB, PORTC, and le registers. The top 16 registers are usually left as being unique to each bank. This layout leaves a maximum of 25 bytes for an array, with 16 being the maximum in any bank other than bank 0. The low-end register organization looks like Fig. 8.5, and in low-end PIC microcontroller devices, even though a total of 7 address bits are used when all four banks are taken into account, only a maximum of 73 unique addresses are implemented, with 48 of them accessible only by the FSR. In most mid-range devices, the registers in each bank are unique to that bank, although there are shadowed registers to allow data movement between banks. In low-end devices, the rst 16 registers of each bank are shared (or shadowed ) between the maximum four banks. Another issue to be aware of with low-end devices and their restricted register banking operation is that the FSR index register can never be equal to 0. Because of this, make sure that you never write any application code such as
