Dear experts
We need to configure a single digital microphone MP45DT02 configured as a left channel with the TLV320AIC3106 codec.
Following the manual (SLAS509F -DECEMBER 2006-REVISED DECEMBER 2014) on page 37 point 11.3.9 Digital Microphone Connectivity says:
"If a digital single mic channel is needed then the corresponding ADC channel should be powered up, and the unused channel should be powered down. When digital microphone is enabled, neither ADC can be used for digitizing analog inputs. Configuring the digital microphone configuration set up is done by writing to Page 0, Register 107, bits D5-D4, and Register 25, bits D5-D4."
Please, do you can tell us what registers we should change in order to configure the CODEC with our microphone MP45DT02?
- Registers for power UP / DOWN the ADC left and right?
- Register 107 values?
- Register 25 values?
The audio recorded with the microphone seems very weak, and other codecs with same digital microphone are working flawlessly.
Best regards,
Sergio
