SBCGCDEF: 
SideBanb Control Gating Clock Defeature .Clock gate defeature bit which 
allows the ISM to transition to idle, but prevents the final clock masking from occurring. 
The value of this bit goes to the 'cgctrl_clkgatedef' port of the SideBand EndPoint

SBCGEN: 
SideBanb Control Gating Clock Enable. Clock gate enable which prevents ISM 
from leaving ACTIVE. Also prevents the clocks from being gated. The value of this bit 
goes to the 'cgctrl_clkgaten' port of the SideBand EndPoint

SBCGCNT: 
SideBanb Control Gating Clock Counter. Idle count limit for ISM which is 
used to determine the block is idle.Recommended value 8'd16 . The value of those bits 
goes to the 'cgctrl_idlecnt' ports of the SideBand EndPoint
