explain about ccp module in PIC 16F877A ?

[rangerskm]

can any one explain the operation of capture compare and PWM register with example program in assembly language and embedded C.

page 65 onward,

what are you wanting to do with it, Ive used the PWM

PR2     = 255;                //Timer2 Period Register - Period of PWM (MAX 255)
CCP1CON = 0b00111100;         //<5:4> DC LSBs, <3:2> PWM Mode
T2CON   = 0b00000100;         //<2> enables Timer2, <1:0> prescaler = 1
CCPR1L = sinedc[dctrans];

That initializes the PWM and set DC to values of a char string.

If u use the data sheet that'll tell u everything u need to switch on (or off) to get it to do what u want
hope this helps

can you explain with sample calculation for PWM operation

CCP-Campture Compare PWM... this is the combination of three(capture, compare, pwm) module... it will associated with timer.... for more detail refer this link
