PIC18F66K80 FAMILY
17.2
The Timer4 module has an eight-bit Period register,
PR4, that is both readable and writable. Timer4 incre-
ment 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 outputs of TMR4 (before the postscaler) are used
only as a PWM time base for the ECCP modules. They
are not used as baud rate clocks for the MSSP module
as is the Timer2 output.
