SFR Definition 21.15. TMR3RLH: Timer 3 Reload Register High Byte
SFR Definition 21.14. TMR3RLL: Timer 3 Reload Register Low Byte
TMR3RLL holds the low byte of the reload value for Timer 3 when operating in auto-reload
mode, or the captured value of the TMR3L register when operating in capture mode.
The TMR3RLH holds the high byte of the reload value for Timer 3 when operating in
auto-reload mode, or the captured value of the TMR3H register when operating in capture
mode.
In 16-bit mode, the TMR3L register contains the low byte of the 16-bit Timer 3. In 8-bit mode,
TMR3L contains the 8-bit low byte timer value.
In 16-bit mode, the TMR3H register contains the high byte of the 16-bit Timer 3. In 8-bit
mode, TMR3H contains the 8-bit high byte timer value.
