CVI specific registers
Reg_CVI_Legacy_0 0x140 RW Drives legacy CVI conduit output signals and returns the current values.
Reg_CVI_Legacy_1 0x144 RW Drives legacy CVI conduit output signals and returns the current values.
Reg_CVI_Legacy_2 0x148 RW Drives legacy CVI conduit output signals and returns the current values.
CVO specific registers
Reg_CVO_Legacy_0 0x14C RW The current value of the CVO conduit side-band signals vid_sof.
