bit 7 bit 0

Legend:

R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’

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

bit 7

Unimplemented: Read as ‘0’

bit 6-3

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

bit 2

DIR: Last BD Direction Indicator bit

1 = The last transaction was an IN token

0 = The last transaction was an OUT or SETUP token

bit 1

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 0 Unimplemented: Read as ‘0’

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