On Revision 2 boards, use the sync_out member of the DQ_VR608_CFG_R2
structure to configure the output signals on the SYNC bus. The
DQ_VR608_SYNC macro takes arguments for each of the sync out lines
(D3...D0). Signal selection works the same as for digital outputs.
Digital outputs can be used to generate simulated VR signals on Rev.2 boards.
A simulator can only be assigned to its corresponding DOut, e.g., Sim0 to
DOut0.
To verify that parameters were set as desired, read back the configuration as:
Once all desired channels have been configured, enable operation with a mask:
The VR-608 is now in operating mode.
