The endpoint x IN/OUT FIFO mapping is shown in Figure 2.8.14.
Endpoints 0 to 4 respectively have their OUT FIFOs. When data are received from the host PC, read
the receive data from these registers. Access these registers in word cycle or byte cycle to the lower
byte.
The configuration of USB x(x=0~4) OUT FIFO data register is shown in Figure 2.8.13.

Bit Symbol
This area is allocated for IN/OUT FIFOs of the endpoint 1 to 4.
The FIFO size and start position can be specified for every 64-byte by
USB EPx IN FIFO configuration register and USB EPx OUT FIFO configuration register.
