22.3.11 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 successfully, 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.

22.3.12 EP0s Data Register (EPDR0s)
EPDR0s is an 8-byte FIFO buffer specifically for receiving endpoint 0 setup commands. Only the
setup command to be processed by the application is received. When command data is received
successfully, the SETUPTS bit in interrupt flag register 0 is set.
As a latest setup command must be received in high priority, if data is left in this buffer, it will be
overwritten with new data. If reception of the next command is started while the current command
is being read, command reception has priority, the read by the application is forcibly stopped, and
the read data is invalid.
