Description:
This register sets the balance between the original
sound and its delayed version for the echo and cho-
rus effects according to the formula.
echo (or chorus) output = original_sound * (1 - bal-
ance) + delayed_sound * balance
where balance = Balance[7:0] / 255
where balance can vary in the range of 0 to 1. A bal-
ance limit of 0.5 is recommended. BALANCE[7:0] =
balance * 255.
