I am using AD9833 ,i am frequently updating output frequencies so for that ,should all times i need to follow all procedure mentioned below or can i skip to update phase register every time after initialize 1st time as i don't need phase shift ?
Should i executed all steps below every time ?
Suggest if some of below that can i ignore.
1) Control word
2) Frq 0 regi-14 bit LSB
3) Frq 0 regi-14 bit
4) Phase0 regi
5) Release reset
Second is, can i hold FSYNC pin permanantly low by firmware once after it transit from high to low with its clock referance ?
