bit 7 bit 0

Legend: U = Unimplemented bit, read as ‘0’

R = Readable bit W = Writable bit HSC = Hardware Settable/Clearable bit

-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown

bit 15-8 Unimplemented: Read as ‘0’

bit 7-4 ENDPT<3:0>: Number of the Last Endpoint Activity bits

(Represents the number of the BDT updated by the last USB transfer).

1111 = Endpoint 15

1110 = Endpoint 14

....

0001 = Endpoint 1

0000 = Endpoint 0

bit 3 DIR: Last BD Direction Indicator bit

1 = The last transaction was a transmit transfer (Tx)

0 = The last transaction was a receive transfer (Rx)

bit 2 PPBI: Ping-Pong BD Pointer Indicator bit

(1)

1 = The last transaction was to the ODD BD bank

0 = The last transaction was to the EVEN BD bank

bit 1-0 Unimplemented: Read as ‘0’

Note 1: This bit is only valid for endpoints with available EVEN and ODD BD registers.
