Description
31:8
Reserved.
7:0
Frequency Divider, F[7:0].
The internal BEEP frequency is the result of dividing the 48kHz clock by 4 times the number specified
in F[7:0].
The lowest tone is 48kHz/(255*4)=47Hz.
The highest tone is 48kHz/(1*4)=12kHz.
A value of 00h in F[7:0] disables internal BEEP generator and allows external PCBEEP input.
Codec Response for Other NID

‘Divider’ in Set Command
Bit
Description

7:0
Frequency Divider, F[7:0].
The internal BEEP frequency is the result of dividing the 48kHz clock by 4 times the number specified
in F[7:0].
The lowest tone is 48kHz/(255*4)=47Hz.
The highest tone is 48kHz/(1*4)=12kHz.
A value of 00h in F[7:0] disables the internal BEEP generator and allows external PCBEEP input.
Note: All nodes except Audio Function Group (NID=01h) will ignore this verb.
