CALIBRATION MEMORY
The 1 kbit calibration EEPROM memory is organized as 128 x 8 bits. It stores the 12-bit calibration PWM values for each output
at 16°C intervals. 10 temperature points are used to cover the range from –40 to 120°C. The temperature or light sensor calibration
data, self heating factor and LED currents are also stored in the memory. The memory contents and detailed memory map are
shown in the following tables.
