LMH1983: Registers that change for each video format when in Auto Format Detection Mode

Hi all,

If you have a document that summarizes the register table data that changes with each video format in Auto Format Detection Mode, would it be possible?

Is it possible?

Does Figure2 show the registers changing with the Auto Format Detection Mode?

Best Regards,

Ryusuke

Hi Kadeem,

How is the progress?

Also, right after soft reset of address 0x05, writing to another register fails.

Is there any waiting time after soft reset?

There is no particular description in the data sheet.

Best Regards,

Ryusuke

Hi Ryusuke-san,

The format code is in below section.

I don't think there is a delay time requirement for a soft reset. To verify this, you may write POWERDOWN = 1 after a soft reset. If the current change, that means there is no programming issue after a soft reset.
