CS3
For the MAX11612/MAX11613, CS3 and CS2 are internally set to 0. For the MAX11614/MAX11615, CS3 is internally set to 0.
When SEL1 = 1, a single-ended read of AIN3/REF (MAX11612/MAX11613) or AIN11/REF (MAX11616/MAX11617) is ignored; scan
stops at AIN2 or AIN10. This does not apply to the MAX11614/MAX11615 as each provides separate pins for AIN7 and REF.

AIN0
Register bit. 1 = setup byte (see Table 1), 0 = configuration byte.
Scan select bits. Two bits select the scanning configuration (Table 5). Default to 00 at power-up.
Channel select bits. Four bits select which analog input channels are to be used for conversion
(Tables 3 and 4). Default to 0000 at power-up. For the MAX11612/MAX11613, CS3 and CS2 are
internally set to 0. For the MAX11614/MAX11615, CS3 is internally set to 0.
1 = single-ended, 0 = differential (Tables 3 and 4). Defaults to 1 at power-up. See the Single-
Ended/Differential Input section.
