VS6663CC
increment CCI sequence, it is not possible for the sensor to consume only part of the new
exposure and gain data.
However if it is not possible for the host to use auto-increment CCI register accesses and
only discrete register accesses are possible then the VS6663CC has a mechanism to
temporarily suspend the automatic application of updated exposure register values.
A group of parameter changes is marked by the host using a dedicated Boolean control
parameter, grouped_parameter_hold (register 0x0104). Any changes made to ‘retimed’
parameters while the grouped_parameter_hold signal is in the ‘hold’ state will be considered
part of the same group. Only when the grouped_parameter_hold control signal is moved
back to the default ‘no-hold’ state will the group of changes be executed by VS6663CC.
