End Of Interrupt Register. The AC’97 End Of Interrupt Register is a write-only
register that allows the CODECREADY and WIS interrupts to be cleared. A
write to this location clears the interrupt.

Global Control Register. The AC97GCR register is the main control register for
the AC’97 Controller. All bits are cleared on reset.
The AC97IFE creates the clock enable signal for the clock controller block. It
is used to enable/disable both PCLK and AC97LK.

CODECREADY Interrupt Status Clear. A write of “1” to this
location will clear the CODECREADY interrupt bit.
Wake-up Interrupt Status Clear. A write of “1” to this
location will clear the WIS interrupt bit.
