RESET
The converter has two reset mechanisms, a power-on reset (POR) and a software reset using CFR_D0. These
two mechanisms are NOR-ed internally. When a reset (software or POR) is issued, all register data are set to
the default values (all 1s) and the SDO output (during the cycle immediately after reset) is set to all 1s. The state
machine is reset to the power-on state.

SCLK skew between converters and data path delay through the converters configured in chain mode can affect
the maximum frequency of SCLK. The delay can also be affected by supply voltage and loading. It may be
necessary to slow down the SCLK when the devices are configured in chain mode.
