7.21.4
Table 33 Data transfer of type ‘DATA1’
7.21.4.1
A 6-bit value to indicate the peak level value of the playback data. The largest value of the left and right channel data in
the playback signal path is held since the last read-out of the microcontroller.
Table 34 Peak level read-out data
Notes
1. Peak value (dB) = (Peak level − 63.5) × 5 × log 2.
2. For peak data >010011, the error in the peak value is
3. For peak data <010100, the error is larger due to limited bit length.
