WebApr 28, 2024 · Writing a value to an entire PORTx register latches the value to the Q outputs of the Port D flip flops (D-FF). If the bit of the corresponding TRISx register is an output, the /Q output of the Tris D-FF enables a buffer connecting the Q output of the Port D-FF to the pin; if the TRISx bit is an input, then it is not connected to the pin. WebIn PIC, explain why we must write “1” to TRISx register in order for the port to be used for input. 5. Explain why we need to buffer the switches used as input to avoid damaging the PIC port. 6.
