CSEL Line of AD-7543A




I have searched for a datasheet of AD-7543A, but could not find it. Can anyone help me about the CSEL line of AD-7543A. When it is grounded is it Master or Slave?

Best regards,


I have made a test. When the CSEL pin is grounded it acts as a MASTER and when it is left open it acts as a SLAVE.


NEC offers a tool for these drives to reverse this behaviour.
You can change NEC drives to CSEL, inverse CSEL, master and slave but only the first two values are available with existing tools right now
