15.29 Timer 2 Capture/Reload Low Byte Register (RCAP2L)
This register is used to capture the TL2 value when Timer 2 is configured in capture mode. RCAP2L is
also used as the low byte of a 16-bit reload value when Timer 2 is configured in auto-reload mode.
15.30 Timer 2 Capture/Reload High Byte Register (RCAP2H)
This register is used to capture the TH2 value when Timer 2 is configured in capture mode. RCAP2H is
also used as the high byte of a 16-bit reload value when Timer 2 is configured in auto-reload mode.
15.31 Timer 2 Low Byte Register(TL2)
This register contains the low byte of Timer 2.

Function
Reserved. Read data will be indeterminate.
Timer 2 Output Enable. This bit enables/disables the clock output function of the T2 pin
(P1.0).
0: The T2 pin functions as either a standard port pin or as a counter input for Timer 2.
1: Timer 2 will drive the T2 pin with a clock output if C/T2=0. Also, Timer 2 roll-overs
will not cause interrupts.
Down Count Enable. This bit, in conjunction with the T2EX pin, controls the direction
that Timer 2 counts in 16-bit auto-reload mode.
