18) Volume Control
Format
Description
The KD16901 provides 110 levels in volume control. The desired volume level is invoked by selecting its index
using incoming byte, Volume_index [7:0]. The index of the highest volume level corresponds to 0x00 (0 dB
attenuation), and that of the lowest volume level corresponds to 0x6d (–
dB attenuation).
Minimum volume index 0x6d corresponds to –
dB attenuation
Maximum volume index 0x00 corresponds to 0 dB attenuation
19) Balance Control
Format
Description
The MSB of Balance_control [7:0] represents balance left if it is 0 and balance right if it is 1. The volume index used
in volume control is also used for balance control, i.e., 0x00 to 0x6d as follows:
For balance left, Balance_control [7:0] has the range of 0x00 (equal balance) to 0x6d (max balance)
For balance right: Balance_control [7:0] has the range of 0x80 (equal balance) to 0xed (max balance)
In balance left (right), the volume level of the left (right) channel is kept, whereas the volume of the right (left)
channel is attenuated by the scale corresponding to Balance_index [7:0].
