Quick Setup Configuration
The quick setup configuration registers provide simple
device configuration options for commonly used signal
paths and settings. Each quick setup register contains
write only, push-button configuration bits. When written
high, a quick configuration bit will internally set all other
appropriate register bits to program the device to the
selected configuration. Writing a logical low to a quick
configuration bit has no effect, and when read back all
quick configuration bits always show a logic-low.
Quick setup bits change the state of registers appropriate
to the selected configuration only. As such, they do not
remove or reset existing device settings that do not share
the same configuration registers. This allows comple-
mentary selections from several different quick configura-
tion registers to be used together in a logical sequence
to configure the device. Do not combine multiple quick
setup bits that configure either the same section or any

shared data path as part of a single sequence. This type
of sequence might not produce the desired results as later
quick setup bits may overwrite registers programmed by
earlier selections.
The digital audio interface (DAI) quick setup register
(Table 79) is used to select the DAI data format. The
configurations in this register program the master mode
clock configuration register (Table 29), the DAI format
configuration register (Table 39), and the DAI TDM control
register (Table 40).
The playback path quick setup register (Table 80) is
used to configure the digital playback path and to select
and program an analog output. The configuration bits in
this register program the DAI I/O configuration register
(Table 38), the output enable register (Table 8), and the
selected analog output mixer, volume, and control regis-
ters (headphones, receiver, speaker, or line output).
