Filtered Data
Each electrode has an associated filtered output. This output is generated through register settings and a low pass filter
implementation (Section 8.4).
5.3.1
The Filtered Data Low register contains the data on each of the electrodes. It is paired with the Filtered Data High register for
reading the 10 bit A/D value. The address of the ELE0 Filtered Data Low register is 0x02. The address of the ELE1 Filtered Data
Low register is 0x04. The address of the ELE2 Filtered Data Low register is 0x06.

5.3.2
The Filtered Data High register contains the data on each of the electrodes. It is paired with the Filtered Data Low register for
reading the 10 bit A/D value. The address of the ELE0 Filtered Data High register is 0x03. The address of the ELE1 Filtered Data
High register is 0x05. The address of the ELE2 Filtered Data High register is 0x07.
