Notes:
1.
All AC link signals are normally low through the trailing edge of RESET. Bringing SDATA_OUT high for the trailing edge
of RESET causes AC’97 AC-link outputs to go high impedance, which is suitable for ATE in circuit testing.
2.
When the test mode has been entered, AC’97 must be issued another RESET with all AC-link signals low to return to
the normal operating mode.
