Design Tips
Question 1:
Answer 1:
When a device with more then 2K words of program memory is used, the calling of subroutines
may require that the PCLATH register be loaded prior to the CALL (or GOTO) instruction to specify
the correct program memory page that the routine is located on. The following instructions will
correctly load PCLATH register, regardless of the program memory location of the label SUB_1.
SUB_1
Question 2:
Answer 2:
Example 6-4
of the code may be removed.
MOVLW
MOVWF
CALL

:
RETURN
shows this. If the device you are using does not use all 4 data memory banks, some
Program execution seems to get lost.
I need to initialize RAM to ’0’s. What is an easy way to do that?
HIGH (SUB_1)
