36.3.17 EP0o Data Register (EPDR0o)

EPDR0o is an 8-byte receive FIFO buffer for endpoint 0. EPDR0o holds endpoint 0 receive data

other than setup commands. When data is received normally, EP0oTS in interrupt flag register 0 is

set, and the number of receive bytes is indicated in the EP0o receive data size register. After the

data has been read, setting EP0oRDFN in the trigger register enables the next packet to be

received. This FIFO buffer can be initialized by means of BP0oCLR in the FCLR0 register.
