8-bit microcontrollers with 80C51 core
6.3.5 Using the serial number
This device has the option of storing a 31 B serial number along with the length of the
serial number (for a total of 32 B) 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.
6.3.6 IAP method
Several IAP calls are available for use by an application program to permit selective
erasing, reading and programming of ash sectors, security bit, conguration bytes, and
device id. All calls are made through a common interface, PGM_MTP. The programming
functions are selected by setting up the microcontroller’s registers before making a call to
PGM_MTP at 1FF0H. The IAP calls are shown in Table 13.
09
Write serial number
:nnxxxx09ss..sscc
Where:
xxxxxx = required eld 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)
0A
Display serial number
:xxxxxx0Acc
Where:
xxxxxx = required eld but value is a ‘don’t care’
0A = display serial number function
cc = checksum
Example:
:0000000AF6
0B
Reset and run user code
:xxxxxx0Bcc
Where:
xxxxxx = required eld but value is a ‘don’t care’
0B = Reset and run user code
cc = checksum
Example:
:0000000BF5
