PIC18 timer help

[Ground_Loop]

I'm trying to use a timer in a PIC18F27Q10.  It looks like registers TMRxL and TMRxH store the period value for the timer according to the MCC setup page.  However, the data sheet says these registers are used for the accumulated value.  I need to set specific accumulated values (reset the count to zero) without altering the overall period value.  I don't see how to accomplish that or understand how the timer operates if the registers are one in the same.  Please help.

Odd numbered timers don't even *HAVE* a period register.  They roll over from 0xFFFF to 0x0000.   However it is possible to configure a CCP module to clear its odd numbered timer on compare match, effectively using its CCPRx SFRs a the limit register for the timer.

In general you should always believe the datasheet (as corrected by any applicable errata) over MCC, unless you have specific evidence to the contrary.

Yea, I figured out the roll over part.  I decided to set it up as a self interrupting timer with timer 3 as the clock source, that stops on roll over and is then externally restarted.  It's not elegant, but it works for my purposes.
