SAMPLING FREQUENCY AND MASTER CLOCK
Master clock frequency (PCLK) can be selected by sampling frequency as shown in Table 21-1. Because PCLK is
made by IIS prescaler, the prescaler value and PCLK type(256 or 384fs) should be determined properly. Serial bit
clock frequency type (16/32/48fs) can be selected by the serial bit per channel and PCLK as shown in Table 21-2.
