The BIST response is composed of 12 bytes followed by a checksum. The structure of
the response is shown in following table:
An example of the BIST response is shown below
0xBA, 0x00, 0x02, 0x07, 0x11, 0x22, 0x33, 0x44, 0x55, 0x66, 0x77,
0x88
0xBA: BIST Response
0x00: Successful test result
0x02,0x07: Software Version 2.7
0x11,0x22,0x33,0x44: Serial/Production Information 0x11223344
0x55,0x66,0x77,0x88: Serial/Production information 0x55667788
Description
0xBA
The test result byte indicates the progress of the self-test. Test errors are indicated in a bit-
wise fashion as listed below:
0x00 : All tests passed
0x01 : Flash CRC verification problem
0x02 : RAM integrity problem
0x04 : Loop back problem
2 byte (MSB first) data representing the software version of the application in Flash Memory.
For example 0x02, 0x07 represents version V2.7
8 bytes, (MSB first), representing the serial number and production information stored in
EEPROM.
