#include <nitro/spi.h>MICResult MIC_AdjustAutoSampling( u32 rate );| rate | Sampling rate. Directly specifies ARM7 CPU timer cycles. Can also be selected from the MICSamplingRate enumerated type. |
Returns the processing result as a MICResult enumerated type. Returns MIC_RESULT_SUCCESS if processing completes successfully, and some other value if the process fails for some reason.
Synchronously adjusts the sampling rate of the microphone's auto-sampling. This function issues an auto-sampling adjustment request to ARM7, waits for a response from ARM7, and returns the process result. This is the synchronous version of the MIC_AdjustAutoSamplingAsync function. This is only valid when auto-sampling has already begun. The CPU timer cycle is updated when the ARM7 receives the request, not earlier.
This function returns MIC_RESULT_INVALID_COMMAND when the CODEC is running in CODEC-TWL mode because auto-sampling cannot be run at an arbitrary frequency in CODEC-TWL mode. In other words, this function can only be used when the CODEC is running in CODEC-DS mode.
This function waits for a PXI interrupt for synchronization purposes. Do not call it when PXI interrupts are prohibited.
