Tris bits
WebTRIS REGISTER: TRIS is a data direction register. Setting TRIS bit for corresponding port will let know the data direction (whether read or write) to microcontroller. Each PORT has its own TRIS register E.g: For PORT A TRISA=0 //making port as output port (write) TRISA=1 //making port as input port (read) WebOct 27, 2024 · If you want a pin to be an input, then set the matching TRIS bit. If you want the pin to be an output, then clear the matching TRIS bit. In short, if the TRIS bit is a 1, then it …

WebTRIS is short for tri-state. This describes the characteristics of the ports of the microcontroller meaning the a port can be an (1) input, (2) output or (3) left hanging. The PIC16F84A has two ports: PORTA and PORTB. This means there are also two TRIS registers: TRISA and TRISB. A zero in any TRIS bit makes the corresponding PORT bit an output. WebTo define the type of an I/O pin, you use the TRISregister. There are two TRIS registers, the TRISAand the TRISBthat corresponds to the 8 pins of each port set, the A and the B.
