This register indicates a virtual link that is to be disabled (unprovisioned) while
individual time-slots are changed. This allows virtual links to either turn on or off
at once instead of gradually while each time-slot in the provisioning RAM is
written.
DVLINK[2:0]
The disable virtual link bits (DVLINK[2:0]) indicate the virtual link to be
disabled. If the CHDIS bit is set high, all time-slots assigned to this virtual link
will be forced unprovisioned, and the value in FDATA[7:0] will be transmitted.
VLDIS
The virtual link disable bit (VLDIS) disables the virtual link in DVLINK[2:0].
When VLDIS is set high, all time-slots assigned to the virtual link in
DVLINK[2:0] will be forced unprovisioned, and the PROV bit of those time-
slots will be ignored. When CHDIS is low, the virtual link's provisioning state is
set by the PROV bit.
