COMMAND/DATA FUNCTION

03 (Cont.)

Subfunction Code = 07 (Full Chip Erase)

Erases all blocks, security bits, and sets status byte and boot vector 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:

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:

= number of bytes (hex) in record

xxxx

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

= “Display Device Data or Blank Check” function code

ssss

= starting address

eeee

= ending address

= subfunction

00 = display data

01 = blank check

02 = display data in data block (valid addresses: 0001~0FFFH)

= checksum

Example 1:

:0500000440004FFF0069

display 4000–4FFF

Example 2:

:0500000400000FFF02E7

display data in data block

(the data at address 0000 is invalid)
