Table 8 shows the bit values of some key registers in
different power modes under various conditions. Use
REFE: Internal Reference Power Enable. When REFE is
set to 1, the internal reference is powered up. When
REFE is set to 0, the internal reference is powered down
allowing an external reference to be connected to REF.
ADCE: ADC Power Enable. When ADCE is set to 1, the
ADC is powered up. When ADCE is set to 0, the ADC is
powered down.

N/A: Programming the part into these modes would not alter the content of the corresponding bit.

this as a quick reference when programming the
MAX1407/MAX1408/MAX1409/MAX1414 family.
BUFE: ADC Input Buffer Power Enable. A logic 1
enables the power-up of the ADC input buffers, while a
logic 0 powers-down the buffers.
MUXE: Multiplexer enable. A logic 0 disables the multi-
plexer outputs while a logic 1 enables them.
