FS Speed Mode Monitor (Read Only)
These bits indicate the actual FS operation mode being used. The actual value is the auto set one when clock
auto set is active and register set one when clock auto set is disabled.
00: Single speed (FS
≤ 48 kHz)
01: Double speed (48 kHz < FS
≤ 96 kHz)
10: Quad speed (96 kHz < FS
≤ 192 kHz)
11: Octal speed (192 kHz < FS
≤ 384 kHz)
