Table 2. Intel-Hex Records Used by In-System Programming
RECORD TYPE
COMMAND/DATA FUNCTION
00
Program Data
:nnaaaa00dd....ddcc
Where:
nn
aaaa
dd....dd
cc
Example:
:10008000AF5F67F0602703E0322CFA92007780C3FD
= number of bytes (hex) in record
= memory address of first byte in record
= data bytes
= checksum
01
End of File (EOF), no operation
:xxxxxx01cc
Where:
xxxxxx
cc
Example:
:00000001FF
= required field, but value is a “don’t care”
= checksum
03
Miscellaneous Write Functions
:nnxxxx03ffssddcc
Where:
nn
xxxx

ff
ss
dd
cc
= number of bytes (hex) in record
= required field, but value is a “don’t care”
= Write Function
= subfunction code
= selection code
= data input (as needed)
= checksum
Subfunction Code = 04 (Set Status Byte to 00h)
ff = 04
ss = don’t care
Example:
:020000030400F7 set status byte to 00h (device executes user code after Reset)
Subfunction Code = 05 (Program Security Bits)
ff = 05
ss = 00 program security bit 1 (inhibit writing to Flash)
01 program security bit 2 (inhibit Flash verify)
02 program security bit 3 (disable external memory)
Example:
:020000030501F5
program security bit 2
Subfunction Code = 06 (Program Flash X2 bit)
ff = 06
ss = 02 program FX2 bit (dd = 80)
6–clk. mode enabled
dd = data
Example 1:
:0300000306028072
program FX2 bit (enable 6–clk. mode)
