The RCAP2, 3, and 4L register captures the low byte of Timer 2, 3, and 4 when Timer 2, 3,
and 4 is configured in capture mode. When Timer 2, 3, and 4 is configured in auto-reload
mode, it holds the low byte of the reload value.
The RCAP2, 3, and 4H register captures the high byte of Timer 2, 3, and 4 when Timer 2, 3,
and 4 is configured in capture mode. When Timer 2, 3, and 4 is configured in auto-reload
mode, it holds the high byte of the reload value.
The TL2, 3, and 4 register contains the low byte of the 16-bit Timer 2, 3, and 4
