D7-0 Calibration data to be read or written to the EEPROM and/or TrimDAC.

During EEPROM or TrimDAC write operations, the data written to this register will be written to the selected device.

During EEPROM read operations this register contains the data to be read from the EEPROM and is valid after EEBUSY = 0 (Page 1, Base + 14).

The TrimDAC data cannot be read back.
