9.3.2.3
The GTBCRs contain the base counts for each of the four PIC timers in each of the two groups, as shown
in
zero. Note that when zero is written to the base count field, (and GTCCRxn[CI] = 0), the timer generates
an interrupt on every timer cycle.

The GTVPRs contain the interrupt vector and the interrupt priority values for the timers as shown in
