メモ
- NAK indicates that a function was unable to accept data from the host (OUT) or that a function has no data to transmit to the host (IN).
- NAK can only be returned by functions in the data phase of IN transactions or the handshake phase of OUT or PING transactions. The host can never issue NAK.
