BIST Response

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

Test Result

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

3-4

<DATA1>

Software Version

2 byte (MSB first) data representing the software version of the application in Flash Memory.

For example 0x02, 0x07 represents version V2.7

5-12

<DATA2>
