Hi Zhou, 
 The serial port control registers for the AD1954 are listed and described on pages 20 - 22 of the datasheet. 
 From looking at the control register available settings, there is no way to change the DAC serial port from a slave to a master; it is always a slave for LRCLK and BCLK. 
 At various places through the descriptions, there are references to (default) modes. These would be the settings upon powerup of the part. If a default is not designated, I would assume that a value of b0 or b00 is the default.
