I am trying to make a code for PIC18F45K50, I am trying to use PORTE as digital input, that means I have to clear ANSELE register which controls this pin behavior
Working on MPLABX 3.30 i tried this line of code:
clrf ANSELE
to clear the register, and I also tried setting the bits of the register individually, but when testing on MPLABX debugger, no matter what I do, the instruction just doesn't do anything and the code goes on. I wish someone can help me or bring me some information about how i can enable this register to be modified in MPLABx
The code im working on is made in ASM
ANSELE has address 0x0F5F so isn't direct addressable because it is not part of access RAM. Check datasheet PIC18(L)F2X/45K50, FIGURE 6-5: DATA MEMORY MAP FOR PIC18(L)F2X/45K50 DEVICES for more information.
Load first the proper BSR value to access these registers, like:
MOVLB high ANSELE
CLRF ANSELE
Or use MPLAB assembler directive like...
BANKSEL ANSELE
CLRF ANSELE
