MCU 'mcu' shutdown: Missed scheduling of next digital out event
This is generally indicative of an intermittent
communication failure between micro-controller and host.
Once the underlying issue is corrected, use the
"FIRMWARE_RESTART" command to reset the firmware, reload the
config, and restart the host software.
