Table 2. Intel-Hex Records Used by In-System Programming

RECORD TYPE

COMMAND/DATA FUNCTION

00

Program Data

:nnaaaa00dd....ddcc

Where:

nn

= number of bytes (hex) in record

aaaa

= memory address of first byte in record

dd....dd = data bytes

cc

= checksum

Example:

:10008000AF5F67F0602703E0322CFA92007780C3FD

01

End of File (EOF), no operation

:xxxxxx01cc

Where:

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

cc

= checksum

Example:

:00000001FF

03

Miscellaneous Write Functions

:nnxxxx03ffssddcc

Where:

nn

= number of bytes (hex) in record

xxxx

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

03

= Write Function

ff

= subfunction code

ss

= selection code

dd

= data input (as needed)

cc

= 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)
