Table 21-60 EEPROM Memory [Opcode: E2h | Destination: 4]
Set EEPROM Memory
Write Parameters
Byte Description
Bytes 0-1

Index of the memory to write (0 means first byte in EEPROM, 1 means second byte and so on)

Bytes 2-3

Number of bytes to be written

Bytes 4-7

EEPROM password if the user needs to write to the TI specified memory space

Bytes 8- Number of bytes passed

Data

Writes data to EEPROM connected to the controller.

The EEPROM holds settings and calibration data. The primary purpose of this function is for the user to write to areas of EEPROM outside of the settings and calibration data. If user wants to overwrite settings/calibration data, the password sent with the command should match the expected password. This is a protection mechanism to prevent accidental overwrite of settings/calibration data.

Return Parameters
Byte Description
Bytes 0- Number of bytes passed

Data

This function reads data from EEPROM connected to the Controller which has settings and calibration data.

Note : EEPROM data can be read without unlocking.
