Register Name:
Access Type:
WKUP and SOF flags in AC97C_SR register are automatically cleared by a processor read operation.
• SOF: Start Of Frame
0: No Start of Frame has been detected since the last read of the Status Register.
1: At least one Start of frame has been detected since the last read of the Status Register.
• WKUP: Wake Up detection
0: No Wake-up has been detected.
1: At least one rising edge on SDATA_IN has been asynchronously detected. That means AC’97 Codec has notified a
wake-up.
• COEVT: CODEC Channel Event
A Codec channel event occurs when AC97C_COSR AND AC97C_COMR is not 0. COEVT flag is automatically cleared
when the channel event condition is cleared.
0: No event on the CODEC channel has been detected since the last read of the Status Register.
1: At least one event on the CODEC channel is active.
• CAEVT: Channel A Event
A channel A event occurs when AC97C_CASR AND AC97C_CAMR is not 0. CAEVT flag is automatically cleared when the
channel event condition is cleared.
0: No event on the channel A has been detected since the last read of the Status Register.
1: At least one event on the channel A is active.
• CBEVT: Channel B Event
A channel B event occurs when AC97C_CBSR AND AC97C_CBMR is not 0. CBEVT flag is automatically cleared when the
channel event condition is cleared.
0: No event on the channel B has been detected since the last read of the Status Register.
1: At least one event on the channel B is active.
