The block diagram in Figure 14 shows the sequence in which the signal passes
through these blocks.
When the DAP block is added in the route, it must be enabled separately to get
audio through. It is recommended to mute the outputs before enabling/disabling the
DAP block to avoid any pops or clicks due to discontinuities in the output.
Refer to section 6.2.4 for programming examples on how to enable/disable the DAP
block.
Each sub-block of the DAP can be individually disabled if its processing is not
required. The sections below describes the DAP sub-blocks and how to configure
them.
Dual Input Mixer
The dual input digital mixer allows for two incoming streams from the source select
switch as shown in Figure 15.
