TMR2RLL holds the low byte of the reload value for Timer 2 when operating in auto-reload mode, or
the captured value of the TMR2L register in capture mode.
The TMR2RLH holds the high byte of the reload value for Timer 2 when operating in auto-reload
mode, or the captured value of the TMR2H register in capture mode.
In 16-bit mode, the TMR2L register contains the low byte of the 16-bit Timer 2. In 8-bit mode,
TMR2L contains the 8-bit low byte timer value.
In 16-bit mode, the TMR2H register contains the high byte of the 16-bit Timer 2. In 8-bit mode,
TMR2H contains the 8-bit high byte timer value.
