Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

bit 6-3

bit 2

bit 1

bit 0

Unimplemented: Read as ‘0’

ENDP<2:0>: Encoded Number of 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

DIR: Last BD Direction Indicator bit

1 = The last transaction was an IN token

0 = The last transaction was an OUT or SETUP token

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

Unimplemented: Read as ‘0’

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