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.

WebNov 16, 2009 · Disable the PWM pin (CCPx) output drivers as an input by setting the associated TRIS bit. Set the PWM period by loading the PR2 register. Configure the CCP module for the PWM mode by loading the CCPxCON register with the appropriate values. Set the PWM duty cycle by loading the CCPRxL register and DCxB<1:0> bits of the CCPxCON … WebSizeis BIT, BYTEor WORD. Number of elementsis how many array locations is desired.
