AD5360 is always busy

Hi. I am working with a DAC IC called AD5360 (datasheet:

it has a 24 bit SPI interface and it supposed to work like this: !Busy is always high and when you send data to DAC, !Busy goes low for brief amount of time and then again it goes high.

the problem is the !Busy signal is always low. I checked connections multiple times but everything seems right but it doesn't work. when I send some data to DAC with stm32f429-discovery(Master), DAC doesn't react. every other pin is doing as it should. it's like DAC is always busy. any help?
