SCART_L_
VOLUME_LSB[1:0]
00 SCART 10 bits volume Left channel 2 LSB in independent mode or SCART10 bits Left and Right
volume 2 LSB in differential mode.
See Figure 20: Volume Control on page 38 or Figure 21: Differential Balance on page 39.
The volume value is defined by the following formula:
Vol (dB) = Decimal value of SCART_L_VOLUME_MSB x 0.5 + Decimal value of SCART_L_VOLUME_LSB x 0.125 -
116 dB (each step is 0.125 dB).
