hi! I am working on a porject and I have a very simple problem on programming PIC16F84A. I cannot write any information on the OPTION_REG(81H) and TRISA(85H) registers since they are out of the scope of movlw command. by using movlw command I can only write to addresses from 0x00 to 0xFF. how can I write on OPTION_REG? Please urgent!
