15.3.20 FIFO Clear Register (FCLR)
FCLR is a register to initialize the FIFO buffers for each endpoint. Writing 1 to a bit clears all the
data in the corresponding FIFO buffer. Note that the corresponding interrupt flag is not cleared.
Do not clear a FIFO buffer during transfer.

Description
Reserved
The write value should always be 0.
EP3 Clear
Writing 1 to this bit initializes the endpoint 3 transmit
FIFO buffer.
EP1 Clear
Writing 1 to this bit initializes both sides of the
endpoint 1 receive FIFO buffer.
EP2 Clear
Writing 1 to this bit initializes both sides of the
endpoint 2 transmit FIFO buffer.
Reserved
The write value should always be 0.
EP0o Clear
Writing 1 to this bit initializes the endpoint 0 receive
FIFO buffer.
EP0i Clear
Writing 1 to this bit initializes the endpoint 0 transmit
FIFO buffer.
