What is the initial value of the AD7864 channel select register?
The customer has not set the logical state of DB0 from DB3. (From the beginning, RD and CS are set low and WR is set high).
Since the logic from DB3 to DB0 has not been set, I thought that the conversion sequence was undecided.
However, we will confirm it because the customer told us that Logic High was detected.
Best Regards
Hello Kshigemori281,
I have not received confirmation as to the state of the registers on start up. At this point I would recommend assuming that the device could potentially come up in a random state…
Hello Jeff,
Thank you for your reply.
Prompt the customer to initialize internal registers to a known value.
Thank you very much.
