PRODUCTION DATA
Configuration parameters can be changed by writing the desired values to the appropriate I2C register(s). The I2C registers are volatile and their contents are lost when power is removed from the device. By writing to the Section 9.6.10, it is possible to store the active configuration in non-volatile E2PROM; during power-up, the contents of the E2PROM are copied into the I2C registers and used to configure the device.
An active high Write Protect (WP) bit prevents the configuration parameters from being changed by accident. Once the E2PROM memory has been programmed with Write Protect (WP) bit set, its content will be locked and can not be reprogrammed any more.
Configuration parameters can be read from the I2C register(s) or E2PROM registers at any time (the WP bit has no effect on read operations).
