xxxx

required field, but value is a “don’t care”

“Miscellaneous Read” function code

ffss

subfunction and selection code

0000 = read signature byte – manufacturer id (15H)

0001 = read signature byte – device id # 1

(C2H)

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

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)
