34.5.7 Output Line Timings
The figure below shows how the outputs are driven either by writing PIO_SODRx/S_PIO_SODRx or PIO_CODRx/S_PIO_CODRx, or by directly writing PIO_ODSRx/S_PIO_ODSRx. This last case is valid only if the corresponding bit in PIO_MSKRx/S_PIO_MSKRx is set. The figure also shows when the feedback in the Pin Data Status register (PIO_PDSRx/S_PIO_PDSRx) is available.
