TX Endpoint Enable.
0 = Disabled (default).
1 = Enabled.
An endpoint should be enabled only after it has been configured.
TX Data Toggle Reset.
Write 1 to reset PID sequence.
Whenever a configuration event is received for this endpoint, software must write a 1 to this bit in order to
synchronize the data PIDs between the host and device.
TX Data Toggle Inhibit.
0 = PID Sequencing Enabled (default).
1 = PID Sequencing Disabled.
This bit is only used for test and should always be written as 0. Writing a 1 to this bit will cause this endpoint
to ignore the data toggle sequence and always transmit DATA0 for a data packet.

TX Endpoint Data Source.
0 = Dual Port Memory Buffer/DMA Engine (default).
Should always be written as 0.
CONTROL — Control.
ISO — Isochronous.
BULK — Bulk.
INT — Interrupt.
