required attention.
00: Endpoint 0
01: Endpoint 1
10: Endpoint 2
When a CTR interrupt occurs (see register ISTR) the software should read the EP
bits to identify the endpoint which has sent or received a packet.
This field shows how many data bytes have been received during the last data
reception.
Note: Not valid for data transmission.
