Table 19-1. USB Register Mode Encoding
Note:
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.
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.
