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.
