Note also when running the IC4 controller simulator, disabling the common TO
bit will disable the UTC / MOVA mode on all controller streams. To simulate
disabling of a single MOVA stream the individual TO1 to TO4 bit must be
deactivated.

7.6.2 Free Standing Interface
A free standing installation will be limited by the capacity of the available I/O on the
BUS/MOVA cards fitted. Within these limits, the control and reply functions can be
mapped as required, using the OSE Config screens – see section 6.11.1.
7.6.3 MOVA Linking
In certain installations it may be of benefit to allow one stream to have some knowledge
of traffic flow in the other. To fulfil this requirement the MOVA lane over-saturation
(SAT) and link end of saturation (ESLI) codes have been made available to the control
bit mapping.
The outputs can be mapped and passed to the controller, either via the 16 conditioning
bits (csi.cond.out.1) or as spare control bits (csi.control.out.1), see section 6.11.1.
7.6.3.1 MOVA Over-saturation (per lane)
Over-saturation is defined as "the condition when a lane is left with a significant queue
at the end of green". MOVA outputs an over-saturation bit for each lane (up to 30),
indicating a ‘0’ if the previous cycle was not over-saturated and a ‘1’ if it was.
