Microcontroller subsystem overview
12.1.7 LCD status display
The status screen is managed by the microcontroller. The display can be
programmed for continuous loop or static message display. A stringcode
table defines characters and text strings to be used for any messages that the
microcontroller generate’s to indicate, for example, that a low-power
shutdown is imminent.
Using a command set, the host is able to select the display contents and
cause them to be displayed. Messages may be altered by sending a new
definition for the status display characters to the microcontroller.
The display of microcontroller generated messages take precedence over
host messages, although once the microcontroller message sequence has
completed the host sequence is displayed.
