0x0C DO_FFC
A “short” or “long” FFC can be optionally specified. (The core will
only switch NUC tables when in manual FFC mode if a long FFC
command is specified.) If sent with no argument, a short FFC is
executed.
Note: Clarification is necessary because shutterless cameras will
likely be in Manual mode.
