MSM6679A-110 Voice Recognition Processor
Asynchronous Serial Protocol Example
All messages to the MSM6679A (except downloads and uploads) are echoed, but replies from the
MSM6679A to the host are not echoed by the host. This arrangement facilitates manual
communication with the MSM6679A using standard terminals. The following table illustrates
the range of MSM6679A functions.
