Table 1. Intel-Hex Records Used by In-System Programming

RECORD TYPE

COMMANDIDATA FUNCTION

00 or 80

Data Record

: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

0l or 81

End of File (EOF), no operation

:xxxxxx0lcc

Where:

xxxxxx = required field, but value is a "don't care”

cc

= checksum

Example:00000001FF

83

Miscellaneous Write Functions

:nnxxxx83 ffssddcc

Where:

nn

= number of bytes (hex) in record

xxxx

= required field, but value is a "don't care”

83

= Write Function

ff

= subfunction code

ss

= selection code

dd

= data input (as needed)

cc

= checksum

Subfunction Code = 0l (Erase Blocks)

ff

= 0l

ss

= block number in bits 7:5, Bits 4:0 = zeros

block 0 : = 00h

block 1 : ss = 20h

block 2 : ss = 40h

block 3 : ss = 80h

block 4 : ss = C0h

Example:0200008301203C erase block 1

Subfunction Code =04 (Erase Boot Vector and Status Byte)

ff = 04

as = don't care

dd = don't care

Example:010000830478 erase boot vector and status byte

Subtunction 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:02000083050175 program security bit 2

Subtunction Code = 06 (Program Status Byte or Boot Vector)

ff = 06

ss =

00 program status byte

01 program boot vector

Note : only two bits of these special cells may be programmed at one time.

Example:020000830601FC78 program boot vector to FC00h
