Beep Frequency & Timing Configuration (Address 12h)
Beep Frequency (FREQ[3:0])
Default: 0000
Function:
The frequency of the beep signal can be adjusted from 260.87 Hz to 2181.82 Hz. Beep frequency will scale
directly with sample rate, Fs, but is fixed at the nominal Fs within each speed mode. Refer to
page 26
Beep On Time Duration (ONTIME[3:0])
Default: 0000
Function:
The on-duration of the beep signal can be adjusted from approximately 86 ms to 5.2 s. The on-duration will
scale inversely with sample rate, Fs, but is fixed at the nominal Fs within each speed mode. Refer to
