[AK5373]
In normal mute operation (OSME bit = “0”), mute is executed on zero cross or zero cross timeout when the LMUTEN and
RMUTEN pins = “L” if zero cross detection is enabled. When zero cross detection is disabled, it is executed immediately.
In case that the LMUTEN and RMUTEN pins = “H”, mute is released on zero cross or zero cross timeout if the zero cross
detection is enabled. When zero cross detection is disabled, it is released immediately.

Figure 16. Normal Mute for LMUTEN, RMUTEN pins
In one-shot mute operation (OSME bit = “1”), mute is executed on zero cross or zero cross timeout after detecting a falling
edge of the LMUTEN and RMUTEN pins. The AK5373 releases the mute on zero cross or zero cross timeout after mute
hold period which is set by MHLD7-0 bits.
