PIC18F47J13 FAMILY
REGISTER 16-1:
16.2
The Timer4/6/8 modules have 8-bit Period registers,
PRx, that are both readable and writable. Timer4/6/8
increment from 00h until they match PR4/6/8 and then
reset to 00h on the next increment cycle. The PRx
registers are initialized to FFh upon Reset.

The outputs of TMRx (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
modules as is the Timer2 output.
