A problem about AD7324

Hi everyone,

   I met a quite curious problem recently. I used AD7324 on my board to sample anolog signals, and the power supply are +-15V, +5V and 3.3V. I am seeing the ADC could be locked up sometimes. Everytime the promblem present, the 4 channels of AD7324 output data 0x8 although the channel number changes nomally.This output data would not recover to normal until power down and up again, even i config the command register to work in normal operation every 500us via SPI. I don't know how does this happen, and by the way, the problem would be occur from power up every time.

  Anyone can tell me why? Thanks a lot!
