Port T input data—
This register always reads back the buffered state of the associated pins. This can also be used to detect overload
or short circuit conditions on output pins.
Port T data direction—
This register controls the data direction of pins 7 through 0.
The ECT forces the I/O state to be an output for each timer port associated with an enabled output compare. In this
case the data direction bits will not change.
The data direction bits revert to controlling the I/O direction of a pin when the associated timer output compare is
disabled.
The timer Input Capture always monitors the state of the pin.
1 Associated pin is configured as output.
0 Associated pin is configured as high-impedance input.
