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.

ISO
R/W
0
Isochronous Transfers
Value Description
0 Enables the transmit endpoint for bulk or interrupt transfers.
1 Enables the transmit endpoint for isochronous transfers.

Mode
Value Description
0 Enables the endpoint direction as RX.
1 Enables the endpoint direction as TX.
Note: This bit only has an effect where 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.
