ADV7612 register settings

I have three documents that I am trying to reconcile

-          Hardware User Guide UG-216 – Rev 0

-          ADV7612 SOFTWARE MANUAL, Pr0, May  2010

-          ADV7612 Register Settings Recommendations. Rev 1.1,  November 2010

  In the register settings  recommendations, there is a recommendation for initializing the device. It  appears that none of these registers are documented in the software manual. Are  there newer versions of these documents? Is there a documented set of values  that you can provide?

Thanks Greg

  • Hi Vito,

    I think the concern here is that the ADV7612 Register Settings Recommendations. Rev 1.1, November 2010, lists HDMI registers at addresses 0x57, 0x58, 0x6F, 0x85, and 0x87.  In the software manual the table does not have a register described at any of these locations.  It implies that there is no register at the location.  One would expect that the software manual would list this registers as "reserved" -  if they exist and must be programmed, but have only design and debug functions which are not going to be revealed to the customer.  However, since the RSR document suggests these register must be programmed to set the part correctly in HDMI mode, and they don't exist in the Software manual, one would tend to believe that the RSR register listing is in error. It could be that I/O registers are meant instead of HDMI map registers.  Can you confirm that the RSR register addresses and recommendations are correct?  If so, then why do these registers not appear in the software manual?

    Thanks,

    Tim
