Port P 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 P data direction—
This register controls the data direction of pin 7.
The enabled PWM channel 7 forces the I/O state to be an output. If the PWM shutdown feature is enabled this pin
is forced to be an input. In these cases the data direction bit will not change.
1 Associated pin is configured as output.
0 Associated pin is configured as input.
Port P data direction—
The PWM forces the I/O state to be an output for each port line associated with an enabled PWM6-0 channel. In this
case the data direction bit will not change.
1 Associated pin is configured as output.
0 Associated pin is configured as input.

Due to internal synchronization circuits, it can take up to 2 bus clock cycles
until the correct value is read on PTP or PTIP registers, when changing the
DDRP register.
