Dear Technical Support Team,

I have a question about LMX2492.

Is it possible to change the reserved register like 142-32767 due to depend on operation condition?

For example, after POR reg143 shows 0x00, sometimes shows 0x01 during operation on the board.

Thease are not public register, but I'd like to know whiter reserved registers change or not.

Best Regards,

y,i

Hi Yi,

Don't write anything to all "reserved" registers. In normal operation, you don't need these registers.

Hi Noel Fung,

Thank you for your reply.

I understand that we shoundn't write reserved register.

Sometimes reg143 shows 0x01 .

Can I ignore it?

Hi Yi,

Right, simply ignore the readback value for these registers.
