Timer Reload Register—High Byte
The Timer x Reload Register—High Byte (see
(MSB) of the 2-byte timer reload value. In CONTINUOUS mode, the timer reload value is
reloaded into the timer upon end-of-count. When the reload bit (TMRx_CTL[RLD]) is set
to 1, it forces the reload function, the timer reload value is written to the timer on the next
rising edge of the clock.
This register shares its address with the corresponding timer data register.

TMR1_RR_H = 0069h, TMR2_RR_H = 0073h, TMR3_RR_H = 0078h)
Timer Input Capture Control Register
The Timer x Input Capture Control Register (see
edges to be captured. For Timer 1, CAP_EDGE_B is used for IC1 and CAP_EDGE_A is
for IC0. For Timer 3, CAP_EDGE_B is for IC3, and CAP_EDGE_A is for IC2.
