(AVDD). The following graph shows the interaction.
Mode Register
The mode register is an 8-bit register from which data can be read or to which data can be written. This register is used to
select the operating mode of the device. MR0 through MR7 indicate bit locations, with MR denoting the bits that are in the
mode register. MR7 denotes the first bit of the data stream. The number in parenthesis indicates the default value of that
bit.
