Non-Volatile Memory, Machine Usage Modes
Principles of Operation
Reissue
Three PWBAs include Non-Volatile Memory (NVM). These are shown in Table 1 . This memory
holds setup parameters which are specific to the particular machine. The NVM for the IOT CPU
PWBA is located on the IOT NVM PWBA. This PWBA includes a 3 volt lithium battery. This
battery supplies RAM power when the PWBA is disconnected from the IOT CPU PWBA or
when prime AC power is removed from the machine. When the IOT CPU PWBA is replaced,
the IOT NVM PWBA must be disconnected from the old PWBA and reinstalled onto the new
PWBA.
