Note 1: the sequence number is a count that indicates whether the data in a particular binary message has been updated or
changed since the last message input.
Note 2: 1 = invalidate all RAM address space before restart
Note 3: 1 = invalidate all data in the EEPROM device (if present) before restart
Note 4: 1 = invalidate all data in the RTC device (if present) before restart
Note 5: 1 = force a cold start reset by clearing RAM and ignoring, but not clearing, the stored position in EEPROM. This provides
cold start testing with the valid time. If cold start testing without time is desired, then the invalidate RTC bit (7.2) should also be set.
