I have read the suggested post again. All examples in this post appear to set each option in the config seperatly, ie pic type, mclr, pwrt as seperate comands but the datasheet for the 16f688 shows a config register called 11.1 (page 100) with each option as seperate bits either set or cleared. Can I just send this as a binary string (or hex equivelent)? if so how?
