The reset period must be set up to include a period of at least 0.5 µs during which the reset signal is held fixed at the low level. Audio processing (audio input/audio output) cannot be performed during the A/D converter calibration period (100 ms), which directly follows the reset. Note on Changes to the DSP Core Main Clock The LC75010W DSP core main clock can be switched by setting the TEST8 pin either low or high as shown below. TEST8 DSP core main clock (Crystal oscillator: 16.9344 MHz) Low (DVSS) 38.1024 MHz High (DVDD 3.3) 40.2192 MHz |
