CS4362

Selects the appropriate digital filter to maintain the standard 15

μs/50 μs digital de-emphasis filter re-

sponse at 32, 44.1 or 48 kHz sample rates. (see Figure 39)

De-emphasis is only available in Single-Speed Mode.

4.4.3

Soft Ramp-Down Before Filter Mode Change (RMP_DN)

Default = 0

0 - Disabled

1 - Enabled

Function:

A mute will be performed prior to executing a filter mode change. When this feature is enabled, this mute

is effected, similar to attenuation changes, by the Soft and Zero Cross bits in the Mode Control 3 register.

When disabled, an immediate mute is performed prior to executing a filter mode change.

Note:

For best results, it is recommended that this feature be used in conjunction with the RMP_UP bit.

4.5

Invert Control (address 05h)

4.5.1

Invert Signal Polarity (Inv_Xx)

Default = 0

0 - Disabled

1 - Enabled

Function:

When enabled, these bits will invert the signal polarity of their respective channels.

4.6

Mixing Control Pair 1 (Channels A1 & B1)(address 06h)

Mixing Control Pair 2 (Channels A2 & B2)(address 09h)

Mixing Control Pair 3 (Channels A3 & B3)(address 0Ch)

4.6.1

Channel A Volume = Channel B Volume (A=B)

Default = 0

0 - Disabled

1 - Enabled

Function:

The AOUTAx and AOUTBx volume levels are independently controlled by the A and the B Channel Vol-

ume Control Bytes when this function is disabled. The volume on both AOUTAx and AOUTBx are deter-

mined by the A Channel Attenuation and Volume Control Bytes (per A-B pair), and the B Channel Bytes

are ignored when this function is enabled.
