Detailed Description
Microphone_PDM_MCU is an alias for the MCU-specific class like Microphone_PDM_nRF52.
Microphone_PDM_MCU is an alias for the MCU-specific class like Microphone_PDM_RTL872x.
This class exists so the subclass Microphone_PDM can just reference Microphone_PDM_MCU as its superclass regardless of which class is actually used.
