Note 1. 16 bits out of 256 bits are reserved for internal oscillator trimming and programmable I2C device address. The remaining 240 bits
can be freely used for storing calibration coefficients and other data.
Note 2. There should be at least a 16ms delay after each EEPROM write since EEPROM programming can take up to 16ms.
Note 3. Data retention values apply when extended EEPROM tests are done. Please contact Micro Analog Systems Oy if the data retention
values here need to be guaranteed by comprehensive EEPROM testing.
