PRODUCTION DATA.
In slave mode, when changing clock sources, the PCM186x requires at least three BCK clocks of no clock or data for the device to reconfigure after clocks resume (if the device is in auto clock config mode).
For example, auto clock config mode: StateA = 48 kHz, change to StateB = 44.1 kHz
For changing from state A to State B:
In master mode, simply switching the I/O pins on the hardware-controlled devices, or changing the sampling rate register should change the sampling rate.
NOTE
Hardware-controlled devices cannot switch from XTAL master mode to external slave mode because the XTAL continues clocking the internal SCLK and not be in sync to the new external clocks. However, this switch can be done in software mode.
