PIC18F8722 FAMILY
16.2
The Timer4 module has an 8-bit Period register, PR4,
which is both readable and writable. Timer4 increments
from 00h until it matches PR4 and then resets to 00h on
the next increment cycle. The PR4 register is initialized
to FFh upon Reset.

The output of TMR4 (before the postscaler) is used
only as a PWM time base for the CCP modules. It is not
used as a baud rate clock for the MSSP, as is the
Timer2 output.
