21.5.5 Synchronous Data Output

Clearing one or more PIO line(s) and setting another one or more PIO line(s) synchronously cannot be done by using PIO_SODRx/PIO_P_SODRx and PIO_CODRx/PIO_P_CODRx. It requires two successive write operations into two different registers. To overcome this, the PIO Controller offers a direct control of PIO outputs by single write access to PIO_ODSRx/PIO_P_ODSRx. Only I/O lines set to 1 in PIO_MSKRx/PIO_P_MSKRx are written.
