Base + 12	Read/Write		EEPROM / TrimDAC Data Register

Bit No.	7	6		5	4	3	2	1	0

Name	D7	D6		D5	D4	D3	D2	D1	D0

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.

Base + 13	Read/Write		EEPROM / TrimDAC Address Register

Bit No.	7	6		5	4	3	2	1	0

Name	A7	A6		A5	A4	A3	A2	A1	A0

A7-A0 EEPROM / TrimDAC address. The EEPROM recognizes address 0 – 127 using address bits A6 – A0. The TrimDAC only recognizes addresses 0 – 7 using bits A2 – A0. In each case remaining address bits will be ignored.
