Digital Volume and Mute Control
Each DAC’s output level is controlled via the Volume Control registers operating over the range of 0 to
-127 dB attenuation with 0.5 dB resolution. See

value (-127 dB). When the XX_MUTE bit is disabled, the corresponding DAC returns to the attenuation
level set in the Volume Control register. The attenuation is ramped up and down at the rate specified by
the SZC[1:0] bits.
The Mute Control pin, MUTEC, is typically connected to an external mute control circuit. The Mute Control
pin outputs high impedance during Power-Up or in Power-Down Mode by setting the PDN bit in the reg-
ister
controlled by the user via the control port, or automatically asserted high when zero data is present on all
DAC inputs, or when serial port clock errors are present. To prevent large transients on the output, it is
desirable to mute the DAC outputs before the Mute Control pin is asserted. Please see the MUTEC pin
in the Pin Descriptions section for more information.
Each of the GPO1-GPO7 can be programmed to provide a hardware MUTE signal to individual circuits.
Each pin can be programmed as an output, with specific muting capabilities as defined by the function
bits in the register
ATAPI Specification
The CS42416 implements the channel-mixing functions of the ATAPI CD-ROM specification. The
ATAPI functions are applied per A-B pair. Refer to
mation.
