Down Count Enable: This bit, in conjunction with the T2EX pin, controls the
FUNCTION
direction that timer 2 counts in 16-bit auto-reload mode.
FUNCTION
This register is used to capture the TL2 value when a timer 2 is configured in
capture mode. RCAP2L is also used as the LSB of a 16-bit reload value
when timer 2 is configured in auto-reload mode.
