Section 23 USB Function Controller
23.5.10 USBFIFO Clear Register (USBFCLR)
USBFCLR is provided to initialize the FIFO buffers for each endpoint. Writing 1 to a bit clears all
the data in the corresponding FIFO buffer. The corresponding interrupt flag is not cleared. Do not
clear a FIFO buffer during transmission/reception.

Bit 7—Reserved
Bit 6—EP3 Clear (EP3 CLR): When 1 is written to this bit, the endpoint 3 transmit FIFO buffer
is initialized.
Bit 5—EP1 Clear (EP1 CLR): When 1 is written to this bit, both FIFOs in the endpoint 1 receive
FIFO buffer are initialized.
Bit 4—EP2 Clear (EP2 CLR): When 1 is written to this bit, both FIFOs in the endpoint 2
transmit FIFO buffer are initialized.
Bits 3 and 2—Reserved
Bit 1—EP0o Clear (EP0o CLR): When 1 is written to this bit, the endpoint 0 receive FIFO
buffer is initialized.
Bit 0—EP0i Clear (EP0i CLR): When 1 is written to this bit, the endpoint 0 transmit FIFO
buffer is initialized.
23.5.11 USBEP0o Receive Data Size Register (USBEPSZ0O)
USBEPSZ0O indicates, in bytes, the amount of data received from the host by endpoint 0.
