37
Reserved byte. The default value is 0.
38
Reserved byte. The default value is 0.
46:39
Firmware Version
: 8-byte firmware version number in
ASCII code.
54:47
Bootloader Version
: 8-byte bootloader version number in
ASCII code.
55
PEC
: An 8 bit CRC calculated over the slave address,
command code, second slave address and returned data.
Algorithm is in SMBus Specifications.
B.2 VPD
The I2C address of vital product data (VPD) is 0x53 (excluding R/W bits).
The I2C address (with R bits) of the slave device is 0xa6. The information is for read only. Do
not modify it with write commands, otherwise, it cannot be restored.
Perform only read operations on the VPD EEPROM. Write operations may destroy VPD data.
If you must perform write operations, use the byte mode. If you must write data in page mode,
write data of less than 16 bytes from the beginning of each page to prevent overwriting data.
