Preliminary specification
Low-voltage low-power stereo audio
CODEC with DSP features
UDA1344TS
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
INNING DEFINITION
The pinning definition in the static pin mode is given in
Table 6.
