80C51 8-bit Flash microcontroller family
64KB Flash, 512B/1024B RAM
Product data
P89C60X2/61X2
RECORD TYPE
03 (cont.)
04
COMMAND/DATA FUNCTION
Subfunction Code = 07 (Full Chip Erase)
Erases all blocks, security bits, and sets status byte to default values
ff = 07
ss = don’t care
dd = don’t care
Example:
:0100000307F5 full chip erase
Subfunction Code = 0C (Erase 4k blocks)
ff = 0C
ss = block code as shown below:
block 0, 0k ~ 4k, 00H
block 1, 4k ~ 8k, 10H
block 2, 8k ~ 12k, 20H
block 3, 12k ~ 16k, 30H
block 4, 16k ~ 20k, 40H
block 5, 20k ~ 24k, 50H
block 6, 24k ~ 28k, 60H
block 7, 28k ~ 32k, 70H
block 8, 32k ~ 36k, 80H
block 9, 36k ~ 40k, 90H
block 10, 40k ~ 44k, A0H
block 11, 44k ~ 48k, B0H
block 12, 48k ~ 52k, C0H
block 13, 52k ~ 56k, D0H
block 14, 56k ~ 60k, E0H
block 15, 60k ~ 64k, F0H
Example:
:020000030C20CF erase 4k block 2
Display Device Data or Blank Check – Record type 04 causes the contents of the entire Flash array to be sent out
the serial port in a formatted display. This display consists of an address and the contents of 16 bytes starting with that
address. No display of the device contents will occur if security bit 2 has been programmed. Data to the serial port is
initiated by the reception of any character and terminated by the reception of any character.
General Format of Function 04
:05xxxx04sssseeeeffcc
Where:
05
= number of bytes (hex) in record
xxxx
= required field, but value is a “don’t care”
04
= “Display Device Data or Blank Check” function code
ssss
= starting address
eeee
= ending address
ff
= subfunction
00 = display data
01 = blank check
02 = display data in data block (valid addresses: 0001 ~ 0FFFH)
cc
= checksum
Example 1:
:0500000440004FFF0069 display 4000–4FFF
Example 2:
:0500000400000FFF02E7 display data in data block (the data at address 0000 is
invalid)
