7.2.5
Using the serial number
This device has the option of storing a 31-byte serial number along with the length of
the serial number (for a total of 32 bytes) in a non-volatile memory space. When ISP
mode is entered, the serial number length is evaluated to determine if the serial
number is in use. If the length of the serial number is programmed to either 00H or
FFH, the serial number is considered not in use. If the serial number is in use,
reading, programming, or erasing of the user code memory or the serial number is
blocked until the user transmits a ‘verify serial number’ record containing a serial
number and length that matches the serial number and length previously stored in the
device. The user can reset the serial number to all zeros and set the length to zero by
sending the ‘reset serial number' record. In addition, the ‘reset serial number’ record
will also erase all user code.
7.2.6
In-Application Programming method
Several In-Application Programming (IAP) calls are available for use by an application
program to permit selective erasing, reading and programming of Flash sectors,
security bit, configuration bytes, and device id. All calls are made through a common
09
Write serial number
:nnxxxx09ss..sscc
Where:
xxxxxx = required field but value is a ‘don’t care’
09 = write serial number function
ss..ss = serial number contents
cc = checksum
Example:
:03000009010203EE (write s/n = 010203)
Display serial number
:xxxxxx0Acc
Where:
xxxxxx = required field but value is a ‘don’t care’
0A = display serial number function
cc = checksum
Example:
:0000000AF6
Reset and run user code
:xxxxxx0Bcc
Where:
xxxxxx = required field but value is a ‘don’t care’
0B = Reset and run user code
cc = checksum
Example:
:0000000BF5
0A
