Preliminary data
XA-G39
RECORD TYPE
84
85
COMMAND/DATA FUNCTION
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.
General Format of Function 84
:05xxxx84sssseeeeffcc
Where:
05
xxxx
84
ssss
eeee
ff
cc
= number of bytes (hex) in record
= required field, but value is a “don’t care”
= “Display Device Data or Blank Check” function code
= starting address
= ending address
= subfunction
00 = display data
01 = blank check
= checksum
Example:
:0500008440004FFF00E9 display 4000–4FFF

= “Miscellaneous Read” function code
= subfunction and selection code
0000 = read signature byte – manufacturer id (15H)
0001 = read signature byte – device id # 1 (EAH)
0002 = read signature byte – device id # 2 (XA–G39 = 65H))
0700 = read security bits (returned value bits 3:1 = sb3,sb2,sb1)
0701 = read status byte
0702 = read boot vector
cc
= checksum
Example:
:02000085000178 read signature byte – device id # 1
