Hello,
I have some question for the shift register behavior of DAC7760.
My customer will use it as 32bit mode.
Because DAC7760 power and MCU power are completely separated (both are isolated), unexpected power cycle could happen on only DAC side.
In that case, DAC7760 return to 24bit mode although MCU don’t know DAC7760 is reset.
1.
When DAC7760 is configured as 24bit mode and 32bit data was wrongly clocked in and latched, are the first 8bit discarded and are the last 24bit latched?
2.
What is the good way to know whether DAC7760 is unexpectedly reset?
Regards,
Oba
