BDTBA<22:0>: BDT Base Address bits
The 23-bit value is made up of the contents of the U1BDTP3, U1BDTP2, and U1BDTP1 registers.
ENDPOINT<3:0>: Transfer Endpoint Number bits
0000 = Endpoint 0
0001 = Endpoint 1
....
1110 = Endpoint 14
1111 = Endpoint 15
DIR: Transfer Direction bit
1 = Transmit: SETUP/OUT for host, IN for function
0 = Receive: IN for host, SETUP/OUT for function
PPBI: Ping-Pong Pointer bit
1 = ODD buffer
0 = EVEN buffer
