Inputs
Controlling LVDS link operation mode: nbcsLkcCntl
This function allows user to control the current operation mode of a specified link in the SBS and
NSE devices. In NSE devices, a link is by default in standby mode. The user can reset the link
(which puts the link in normal mode after reset) or put it in a standby (low power) mode.
Resetting or putting the link in normal mode brings the link out of standby mode. The valid

devices, this function enables/disables the selected LVDS links. If the receive direction is
selected, it also controls whether the working or the protection LVDS link is the active link. This
active link selection is, however, only functional when the software control option is enabled
which is specified in the MIV during chipset initialization. In addition, the following parameters,
path termination mode, ILC FIFO threshold level and FIFO timeout constant, supplied by the user
during initialization via DIV will be restored when the link is selected to bring out from low-
power state. This is due to the fact that these parameters cannot be updated at the hardware level
when the link is in low-power state.
This function also accepts group handle and acts on all members in the group. If the group
contains mixed devices, the only valid entry for
