General Format of Function 05
:02xxxx05ffsscc
Where:
02
xxxx
05
ffss
= number of bytes (hex) in record
= required field, but value is a “don’t care”
= “Miscellaneous Read” function code
= subfunction and selection code
0000 = read signature byte – manufacturer id (15H)

0002 = read signature byte – device id # 2
0003 = read FX2 bit
0080 = read ROM Code Revision
0700 = read security bits
0701 = read status byte
0702 = read boot vector
= checksum
cc
Example 1:
:020000050001F8 read signature byte – device id # 1
Example 2:
:020000050003F6 read FX2 bit
(bit7=0 represent 12–clock mode, bit7=1 represent 6–clock mode)
