UPDATE FUNCTION
To prevent clock contention issues during setup of the digital audio interface mux, an update system
has been implemented. This allows the registers to be configured as required and the update to be
applied with the last register write synchronise the configuration of the digital audio mux. An update
can be generated using any of the update bits shown in Table 38.
