Beep Off Time & Volume (Address 13h)
Beep Off Time (OFFTIME[2:0])
Default: 000
Function:
The off-duration of the beep signal can be adjusted from approximately 75 ms to 680 ms. The off-duration
will scale inversely with sample rate, Fs, but is fixed at the nominal Fs within each speed mode. Refer to
Figure 10 on page 26
BEEP bits.
Beep Volume (BPVOL[4:0])
Default: 00000
Function:
The level of the beep into the output mixer can be adjusted in 2.0 dB increments from +12 dB to -50 dB.
Refer to
and BEEP bits. Levels are decoded as described in the table above.
