Use lots of comments to make notes to yourself! Note 1: anything after ' ' is a comment and ignored. MOVLW b'01100001' 4MHz Clk, IntOsc, SysClk via IntOsc Note that I'm using MPLAB v8.92 compiler which changes labels and code one types into machine code (a HEX file) programmed into the PIC. Look at this code that will setup the internal clock in the template. The p12f683.inc file defines names based on the register/bank labels.
2 by setting and clearing bits in the associated register. They control the hardware and other functions. PIC12F683 registers are accessed in two banks.
