Sound Control Register (AICSCTR)
The AIC sound sampling control register controls the sound input and voice recording
operations. If the SDC bit is set to 1, the input sound data sampling operation is enabled. If SDC
is reset to 0, the operation stops (disabled). The SDC bit should be cleared at the beginning of
the Interrupt Service Routine to disable the sound sampling.
