Truth Tables
Table 28.USB Register Mode Encoding
The ‘In’ column represents the SIE’s response to the token
type.
A disabled endpoint will remain such until firmware changes it,
and all endpoints reset to disabled.
Any Setup packet to an enabled and accepting endpoint will
be changed by the SIE to 0001 (NAKing). Any mode which
indicates the acceptance of a Setup will acknowledge it.
Most modes that control transactions involving an ending ACK
will be changed by the SIE to a corresponding mode which
NAKs follow on packets.

Out
A Control endpoint has three extra status bits for PID (Setup,
In and Out), but must be placed in the correct mode to function
as such. Also a non-Control endpoint can be made to act as a
Control endpoint if it is placed in a non appropriate mode.
A ‘check’ on an Out token during a Status transaction checks
to see that the Out is of zero length and has a Data Toggle
(DTOG) of 1.
