Hi everyone,

 I have been playing around with the Harris HSP45102
 DDS chip and I am
 having a little trouble using it. I am assuming the
 serial data is being
 tranfered from the PIC to the DDS OK because of the
 fact that when the
 data is being transmitted, the DDS outputs 'stuff'
 (not even close to a sine wave but is is doing something) and when
 nothing is being
 transfered it outputs nothing. I do not fully
 understand the way the
 registers work in the DDS and cannot find any info on it other than the

 data sheet which doent  tell the sequence of events to give me an
 output. I know that the ENPHAC, TXFR and LOAD pins
 play a big part of the operation but are unsure on how to use them in a

 proceedure to give me an sine output.
 When I keep them all low it has the above affect and
 when I play around
 with them in my PIC program it usually outputs
 nothing. Does anyone know
 the steps to take to give a sine output on the
 HSP45102.
 Any help will be greatly appreciated
