Notes:

1. All AC-link signals are normally low through the trailing edge of RESET#. Bringing SDATA_OUT high for the rising edge of RESET#
causes the AK4541 AC-link outputs to go high impedance which is suitable for ATE in circuit testing.
Note that the AK4541 enters in
the ATE test mode regardless SYNC is high or low.
2. Bringing both SYNC high and SDATA_OUT low for the rising edge of RESET# causes AKM test mode.
3.
Once test modes have been entered, the only way to return to the normal operating state is to issue “cold reset” which issues RESET#
with both SYNC and SDATA_OUT low.
