This bit is only valid for endpoints with available EVEN and ODD buffer descriptor registers.
In Host mode, all transactions are processed through Endpoint 0 and the Endpoint 0 BDTs. Therefore,
ENDPT<3:0> will always read as ‘0000’.
Unimplemented: Read as ‘0’
ENDPT<3:0>: Number of the last endpoint activity (represents the number of the endpoint BDT
updated by the last USB transfer)
1111 = Endpoint 15
1110 = Endpoint 14

0001 = Endpoint 1
0000 = Endpoint 0
DIR: Last Buffer Descriptor Direction Indicator bit
1 = The last transaction was a transmit transfer (TX)
0 = The last transaction was a receive transfer (RX)
PPBI: Ping-Pong Buffer Descriptor Pointer Indicator bit
1 = The last transaction was to the ODD buffer descriptor bank
0 = The last transaction was to the EVEN buffer descriptor bank
Unimplemented: Read as ‘0’
