For doing serial and parallel programming on an AD9910

using 2 ARM processors I only need to have as minimum requirement,

 

Processor 1 serial:

SDIO

SCLK

I/O Update

Profile 0

Profile 1

Profile 2

 

Processor 2 Parallel:

 

 

D0-D15

F0

F1

TX Enable

PDCLK

 

Where processor 1 is for programming the register and single tone mode / slow PSK

Where processor 2 is for bitbanging for eg. high speed frequency hopping

 

Too much/less pins or correct?
