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