    18F4520 Tranmsitter and Reciever Question .

    Yes it is possible if u are using ASM coding... The TXEN bit (already set as 0) will help... The pin will act as transmitter only if this bit is set... so if you dont want to transmit disable this bit... i referred ASM only because some compilers like mikroC has separate predefined function for...
