(6) Bypass Mode
Refer to page 5 ∼ 10 for input port setting, and output port setting should be master mode. The bypass mode of the
AK4122 is set by the register.
In bypass mode, the DIT function of the AK4114 can not be used as the output port. 10pin PORT should be used
instead.
Input BICK, LRCK, and DATA are output from the output port side in the bypass mode.
