Display Device Data or Blank Check – Record type 84 causes the contents of the entire FLASH array to be sent out
the serial port in a formatted display. This display consists of an address and the contents of 16 bytes starting with that
address. No display of the device contents will occur if security bit 2 has been programmed. The dumping of the device
data to the serial port is terminated by the reception of any character.
