Static pin mode
The UDA1344TS is set to static pin mode by setting both
pins MC1 and MC2 to HIGH level.
The controllable features in this mode are:
• System clock frequency selection
• Data input/output format selection
• De-emphasis and mute control
• Power-down and ADC input level selection.
P
The pinning definition in the static pin mode is given in
Table 6.
Table 6 Pinning definition in static pin model
S
In the static pin mode the options are 256f
given in Table 7.
