U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

bit 7-0

CNT<7:0>: Start-Of-Frame Size bits
Value represents 10 + (packet size of n bytes). For example:

0100 1010

= 64-byte packet

0010 1010

= 32-byte packet

0001 0010

= 8-byte packet

PPB<1:0>: Ping-Pong Buffers Configuration bits
11

= Even/Odd ping-pong buffers are enabled for Endpoints 1 to 15

= Even/Odd ping-pong buffers are enabled for all endpoints

= Even/Odd ping-pong buffers are enabled for OUT Endpoint 0

= Even/Odd ping-pong buffers are disabled

Note 1:

This bit is only active when the UTRDIS bit (U1CNFG2<0>) is set.
