32.4.5 PDC Flags and Peripheral Status Register

Each peripheral connected to the PDC sends out receive ready and transmit ready flags and the PDC returns flags to the peripheral. All these flags are only visible in the peripheral’s Status register.

Depending on whether the peripheral is half- or full-duplex, the flags belong to either one single channel or two different channels.

These status flags are read in the status register of the peripheral associated to a PDC channel.
