Protocol and Messages
Message
The message conduit is used to issue commands to the CS1810xx/CS4961xx and
retrieve HMI status. The data conduit is used to transfer data dependent on the HMI state
as determined by commands issued by the host via the message conduit.
Messages are used to efficiently invoke action in the CS1810xx/CS4961xx. To send a
message, the host optionally writes to the A, B, and C registers. Writing to the D register
transmits the message to the CS1810xx/CS4961xx. A listing of all HMI messages is
shown in
page
34.
