adc.begin returns -2 #5

Hi, I uploaded ad7124-full-test.ino to Arduino UNO with ADS7124-4, but adc.begin returned -2.

My setup is:

AD7124-4	Arduino UNO
MOSI/MISO/SCK	DIN/DOUT/SCLK
/CS	PIN10
IOVDD	3.3V
AVDD	3.3V
AVSS	GND
DGND	GND

REGCAPD and DGND are connected by 0.1uF capacitor.
REGCAPA and AVSS are connected by 0.1uF capacitator.

In what condition could the error -2 occur?
