There are two types of responses: Solicited and Unsolicited. Solicited responses are provided as a
direct response to an issued command and will be provided in the frame immediately following the
command. Unsolicited responses are provided by the CODEC independent of any command. Unso-
licited responses are the result of CODEC events such as a jack insertion detection. The formats for
Solicited Responses and Unsolicited Responses are shown in Tables 12 and 13 respectively. The
“Tag” field in bits [31:28] of the Unsolicited Response identify the event.
