Part Number:ADS1148
Hi all
Would you mind if we ask ADS1148?
<Question1>
Our customer would like to set DRDY MODE as "1: DOUT/DRDY pin functions both as Data Out and Data Ready".
In order to access IDAC0—IDAC Control Register 0, does it require set START=High?
On the table.15's remark, there is the description "When the START pin is low or the device is in power-down mode, only the RDATA, RDATAC, SDATAC, WAKEUP, and NOP commands can be issued."
So, in order to select WREG command, we assume that START pin requires high level before register access.
<Question2>
About WREG command, does it regure to care the DRDY timing?
We assume that it doesn't matter.
<Question3>
About RREG command, does it regure to care the DRDY timing also?
We assume that it doesn't matter.
<Question4>
In despite of new RDATA command or RDATAC command issue, as DIN keeps outout NOP, is it possible to read AD conversion data?
As the background of this question, it is relation to 9.5.3.6 RDATAC (0001 010x) on the datasheet P39.
We appreciate your help always.
Kind regards,
Hirotaka Matsumoto
