hello,

I use the AD9959 with a micro controller MSP430F169.

I interface with usb kit and a java program that communicates with the micro controller and then to the AD9959. Though I DDS program each frequency, channel 0, CHANNEL1, channel2, and each amplitude channel3, I can not to generate the linear sweep of frequency on other routes apart from the dds channel0 why?

I use P0 P1 P2 P3 but nothing works.

I address CSR0 channel = 0, channel = 1 ... CSR1

On your site (evaluation board) I noticed that each time the register CSR = 1000000 WHY?

THANKS FOR YOUR RESPONSE AND SORRY FOR MY ENGLISH.
