b12..............PR4: AC’97 Power down Control 4
This bit controls the power state of the AC-link in AC’97.
“0”: Normal
(default)
“1”: Power down
b13..............PR5: AC’97 Power down Control 5
Setting this bit to “1” disables the internal clock of AC’97.
In case AC’97 is used with DS-1, the master
clock is supplied from DS-1.
Therefore, when the clock of AC’97 is stopped completely, set both PR5
and PSN bits to “1”.
“0”: Normal
(default)
“1”: Disable
b[15:14] ......AC’97 Power down Control 6 and 7
These bits control PR6 and PR7 status of the power control register in AC’97.
