LMH1228: Resistor configuration

Part Number: LMH1228

Hi team,

My customer is designing with LMH1228 and needs help on software setting.

Could you please take a look below?

 

The Programming guide (SNAU206C) section 3.1.1 shows resistor configuration example.

In the 4th step: read 0xFE resistor and write bit 5

In the 5th step: write 0xFE resistor bit 4

Is it possible to configure those all together, meaning do the same for resistor 0xFE bit [5:4]?

There are some other examples showing operation such that set resistor bit value after enabling the same bit. Is it possible to configure those all together, too?

 

Best regards,

Kurumi
