FS1-0:Select De-emphasis frequency
The AK4516A includes the digital de-emphasis filter(tc=50/15us) by IIR filter. The filter
corresponds to three sampling frequency (32kHz, 44.1kHz, 48kHz). The de-emphasis filter
selected by FS0 and FS1 registers are enabled for input audio data.

DEM: Control of De-emphasis (0: Disable, 1: Enable)
FS0 and FS1 registers of the de-emphasis are enabled by setting DEM=1. FS0 and FS1 are
ignored at DEM=0.
This register is reset by the PD pin="L", then inhibits writing to this register.
