ABSTRACT:
The processing system is electrically connected to a computer and has a non-volatile memory (NVM) for storing firmware and an NVM control interface having a plurality of registers for updating and reading data stored in the NVM. When the NVM control interface updates a current piece of data stored in the NVM, the NVM control interface first reads a prior piece of data that is stored in the NVM prior to the current piece of data and transmits the prior piece of data to the computer for comparison, then the NVM control interface updates the current piece of data.
