[Q]

My customer set the nyquist zone as follows.

0x680042 0x01 //2nd Nyquist zone select or 0x00 // 1st Nyquist zone select
0x68004E 0x80 //nyquist enable
0x680000 0x01 // reset digital. Must issue after writes to 6800h
0x680000 0x00 // clear reset

In this case, how long does it take to become operational after setting that setting ?

This is the information needed to design their software.

Best Regards,

Hiroshi Katsunaga
