im looking at the demo program for development kits transmitter and receiver rfpic12675 and receiver rf rxd XXX. im trying to apply the same program to my telemtry project but with digital input.

i dont understand the part of program which under head transmitter loop. do we need to do the loop if our input is digital? and what about the '' rrf ' and 'bnz' instruction? rotate right flag?
