Port T input data—
A read always returns the buffered input state of the associated pin. It can be used to detect overload or short circuit
conditions on output pins.
Port T data direction—
This bit determines whether the pin is an input or output.
The TIM forces the I/O state to be an output for a timer port associated with an enabled output compare. In this case
the data direction bit will not change.
1 Associated pin is configured as output
0 Associated pin is configured as input
Port T data direction—
This bit determines whether the pin is an input or output.
The TIM forces the I/O state to be an output for a timer port associated with an enabled output compare. Else the
routed PWM forces the I/O state to be an output for an enabled channel. Else the API_EXTCLK forces the I/O state
to be an output if enabled. In these cases the data direction bit will not change.
1 Associated pin is configured as output
0 Associated pin is configured as input
