33.5.5 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 (S_)PIO_SODRx and (S_)PIO_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 (S_)PIO_ODSRx. Only I/O lines set to 1 in (S_)PIO_MSKRx are written.
