TMDS181RGZEVM: missing I2C registers in datasheet?

Jason Lo

Part Number: TMDS181RGZEVM
Other Parts Discussed in Thread: TMDS181,

I am using Eyescan with TMDS181RGZEVM. When I view the register map, I see there is "Page 0" and "Page 1" for registers. The registers in "Page 1" are not listed in the datasheet for the TMDS181 however. Is there additional documentation that explains the function of these registers?

Thanks,

Jason

Hi Jason,

Page 1 registers are used for internal TI debugging, page 0 registers(datasheet) are the ones the user needs for normal operation.

Moises:

When I use Eyescan to set the equalizer mode to Fixed and change the equalizer level for each of the individual lanes, I see these values updated at addresses 0x4E and 0x4F in Page 1. It does not seem to affect any registers in Page 0; addr 0x0D = 0x00 regardless of the fixed equalizer level settings I use.

If Page 1 was just intended for internal TI use, how would I change the equalizer level for each individual lane?

Regards,
Jason
