Port P data direction—
This bit determines whether the associated pin is an input or output.
The PWM forces the I/O state to be an output for an enabled channel. If the PWM shutdown feature is enabled this
pin is forced to be an input. In this case the data direction bit will not change.
1 Associated pin configured as output

Port P data direction—
This bit determines whether the associated pin is an input or output.
The PWM forces the I/O state to be an output for an enabled channel. Else the TIM forces the I/O state to be an
output for a timer port associated with an enabled output compare. Else depending on the configuration of the
enabled SCI the I/O state will be forced to be input or output. In this case the data direction bit will not change.
