NOTE
Do not confuse pin function with the electrical state of the pin at reset. All general-
purpose I/O pins configured as inputs at reset are in a high-impedance state and
the contents of port data registers is undefined. In port descriptions, a “U” indicates
this condition. The pin function is mode dependent.
NOTE
To enable PA3 as fourth input capture, set the I4/O5 bit in the PACTL register. Oth-
erwise, PA3 is configured as a fifth output compare out of reset, with bit I4/O5 being
cleared. If the DDA3 bit is set (configuring PA3 as an output), and IC4 is enabled,
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. PA7 drives the pulse ac-
cumulator input but also can be configured for general-purpose I/O, or output com-
pare. Note that even when PA7 is configured as an output, the pin still drives the
pulse accumulator input.
