01 - Double-Speed Mode (50 to 100 kHz sample rates)

10 - Quad-Speed Mode (100 to 200 kHz sample rates)

11 - Reserved

Function:

Selects the required range of input sample rates.

4.2

Invert Signal (address 02h)

4.2.1

INVERT SIGNAL POLARITY (INV_XX)

Default = 0

0 - Disabled

1 - Enabled

Function:

When enabled, these bits invert the signal polarity for each of their respective channels.
