Description
Auto Set
Value Description
0 The TXRDY bit must be set manually.
1 Enables the TXRDY bit to be automatically set when data of the
maximum packet size (value in USBTXMAXPn) is loaded into
the transmit FIFO. If a packet of less than the maximum packet
size is loaded, then the TXRDY bit must be set manually.

reserved
RO
0
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

MODE

0
Mode
Value Description
0 Enables the endpoint direction as RX.
1 Enables the endpoint direction as TX.
Note: This bit only has an effect when the same endpoint FIFO is
used for both transmit and receive transactions.

DMAEN
R/W
0
DMA Request Enable
Value Description
0 Disables the µDMA request for the transmit endpoint.
1 Enables the µDMA request for the transmit endpoint.
Note:
3 TX and 3 /RX endpoints can be connected to the µDMA
module. If this bit is set for a particular endpoint, the DMAATX,
DMABTX, or DMACTX field in the USB DMA Select
(USBDMASEL) register must be programmed
correspondingly.

FDT
R/W
0
Force Data Toggle
Value Description
0 No effect.
1 Forces the endpoint DT bit to switch and the data packet to be
cleared from the FIFO, regardless of whether an ACK was
received. This bit can be used by interrupt transmit endpoints
that are used to communicate rate feedback for isochronous
endpoints.
