Changing volume level, power-up/down and switching signal path don’t have any pop noise. The following registers
have a transition time shown in Table 13 and Table 15. It depends the sampling frequency (FS3-0 bits) and the setting of
PUT1-0 bits and PTS1-0 bits. It is necessary to take the interval time when the register is changed continually. The
interval time depends on the transition time. The setting of transition time should not be changed during transition.
