The FST/LST digital outputs can be tri-stated but are
enabled as outputs by default. The enabling/disabling
of FST/LST can be retimed to a field boundary. The
state of this control bit is always available via a serial
interface read, i.e. it does not have to wait to change
state at a field boundary

The QCK output can be tri-stated independently. The
enabling/disabling of QCK can be retimed to a field
boundary. The state of this control bit is always availa-
ble via a serial interface read, i.e. it does not have to
wait to change state at a field boundary.

The CIF and QCIF video modes expect a recom-
mended set of input clock frequencies, however the
acceptable range of clock frequencies can be extended
if this bit is set. If this bit is set then the primary input
clock will be divided down by 1.5 prior to the clock gen-
erator, thus if the expected clock input is 16 MHz, we
can set this bit and accept 24 MHz and achieve the
same final frame rate.
