DS280DF810: How to Set Receiver Adapt Mode? Reg0X31

Part Number: DS280DF810
Other Parts Discussed in Thread: DS250DF410, DS250DF810

When I try to modify the adapt mode of DS280DF810:

by reading the "DS250DF810, DS250DF410 Programmer's Guide", writing value(0x20, 0x40,0x60) to Reg 0x31.

After write operation, it always read back the value of 0x00

So, any other Reg need to operate to modify the adapt mode?

    Hi,

    The user needs to first select the channel registers via global register writes prior to being able to implement channel register operations such as adapt mode configuration. See example below.

    Select a Specific Channel

    Operation: Select a specific channel as the target for subsequence channel register accesses.

    Table. Select Channel 0 as Target Channel

    　

    STEP

    SHARED/ CHANNEL REGISTER SET

    OPERATION

    REGISTER ADDRESS [HEX]

    REGISTER VALUE [HEX]

    WRITE MASK [HEX]
