6.2 Endpoint Control Request
The AK5370 supports five sampling frequencies. The sampling rate is changed when Set
Endpoint Control Request is issued. SET_CUR, GET_CUR of bRequest is only supported.
GET_MIN, GET_ MAX, and GET_RES of bRequest are not supported.

Description
The following five values are valid. Others are
invalid.
0x001F40 : 8kHz
0x002B11 : 11.025kHz
0x005622 : 22.05kHz
0x00AC44 : 44.1kHz(default)
0x00BB80 : 48kHz
If the iSampleFreq is different from the above values, the AK5370 forces sampling frequency to the
appropriate value.
