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/
Down Count Enable. This bit, in conjunction with the T2EX pin, controls the
direction that timer 2 counts in 16-bit auto-reload mode.
Timer 2 Capture LSB. This register is used to capture the TL2 value when
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.
Timer 2 Capture MSB. This register is used to capture the TH2 value when
timer 2 is configured in capture mode. RCAP2H is also used as the MSB of a 16-
bit reload value when timer 2 is configured in auto-reload mode.
