This command is used to switch from an
internal crystal controlled clock source to an
external clock source and vice versa.
This command sets the behaviour of the
SAA6752HS in Clock mode 2 if video sync
cannot be achieved. Either mode 2 is
continued or the SAA6752HS will
automatically switch to mode 1 or mode 3, as
selected.
This command outputs the internal crystal
generated clock (27 MHz) to an output
pin CLKOUT for use in other parts of an
application.
