 From what I understood, the 12V are needed to *flash* the firmware. 
This is a thing you would do once. But there's a 64 byte section of 
EEPROM inside which might be updated at runtime (either by the MCU 
itself or by the CoCo, I don't know how this could work). This could be 
used to store the parameters. The MCU firmware reads the parameters on 
power up from this EEPROM (or on changes) and sends them to the AV250.
