Before requesting that the MVTX2801 updates the EEPROM device, the
correct checksum needs to be calculated and written into this checksum
register. The checksum formula is:
FF
2
Σ
i = 0
i C register = 0
After booting cycle the MVTX2801 calculates the checksum. If the checksum is
not zeroed the MVTX2801 does not start.
