Yes, you are correct, the '873 does not have a CCP3.
Also, the datasheet's pin diagram's in the CCP module chapter also show which pins are connected to each of the remaining 2 CCP modules.

a thing that I want to do is dim controll of LED to port B0-B7.
I can't understand defnition of ccp.
so I need sample program.
Do realize port B0-B7 pwm controll at the same timing ?
I know multiple pwm controll by ASM even low-end pic, but I can not do this.
There are more than a few examples (some very recent) of both software and hardware PWM control of pins on this site. All it takes is a bit of searching.
