Table 1. Intel-Hex Records Used by In-System Programming
RECORD TYPE
00 or 80
0l or 81
83
COMMANDIDATA FUNCTION
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
End of File (EOF), no operation
:xxxxxx0lcc
Where:
xxxxxx = required field, but value is a "don't care”
cc = checksum
Example:00000001FF
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
