Figure 8-2. Capture/Compare Block Diagram
The control and status bits that implement the input capture functions are contained in the PACTL,
TCTL2, TMSK1, and TFLG1 registers.
To configure port A bit 3 as an input capture, clear the DDRA3 bit of the PACTL register. Note that this bit
is cleared out of reset. To enable PA3 as the fourth input capture, set the I4/O5 bit in the PACTL register.
Otherwise, PA3 is configured as a fifth output compare out of reset, with bit I4/O5 being cleared. If the
DDRA3 bit is set (configuring PA3 as an output), and IC4 is enabled, then writes to PA3 cause edges on
the pin to result in input captures. Writing to TI4/O5 has no effect when the TI4/O5 register is acting as IC4.
