There are two methods to bring the AC-link out of low power mode. Regardless of the method, it
is always the AC97 Controller that performs the wake-up.
The AC97 Controller can wake up the AC97 Codec by issuing either a cold or a warm reset.
The AC97 Controller can also wake up the AC97 Codec by asserting SYNC signal, however this
action should not be performed for a minimum period of four audio frames following the frame in
which the powerdown was issued.
This feature is implemented in AC97 modem codecs that need to report events such as Caller-
ID and wake-up on ring.
The AC97 Codec can drive SDI signal from low to high level and holding it high until the control-
ler issues either a cold or a warm reset. The SDI rising edge is asynchronously (regarding
SYNC) detected by the AC97 Controller. If WKUP bit is enabled in IMR register, an interrupt is
triggered that wakes up the AC97 Controller which should then immediately issue a cold or a
warm reset.
If the processor needs to be awakened by an external event, the SDI signal must be externally
connected to the WAKEUP entry of the system controller.
