Rev.1 August 2009
Description
010b = output SPDIF_IN1
011b = output SPDIF_IN0
100b = output SPDIF_IN3
101b = output SPDIF_IN4
110b = output SPDIF_IN5
111b = output SPDIF_IN6
Enable or disables the SPDIF transmitter.
0b = enabled
1b = disabled
Sets the edge to be used for the preamble.
0b = rising edge
1b = falling edge
Used to indicate to the receiver if the data in the transmitted stream is
valid audio data.
0b = valid data sent
1b = invalid data sent
Used to indicate to the receiver if the data is copyright material.
0b = copyright
1b = not copyright
Used to specify the type of equipment in use. Not applicable when the
SPDIF Mux Bits[14:12]
are set to anything other than 000b.
Description
Indicates the current status of the PWM ready pin. When PWM
ready is low, the
PWM is not enabled. When PWM ready is high, the PWM is enabled
and stable.
0b = PWM ready pin low
1b = PWM ready pin high
When enabled, all PWM channels selected by Bits[10:7] can be
used.
0b = all PWM channels disabled
1b = selected PWM channels enabled
Used to configure the MCLK_OUT pin.
0b = crystal frequency on MCLK_OUT
1b = internally generated clocks on MCLK_OUT
Enables the enable/disable patterns for the PWM block.
0b = enable/disable pattern not used
1b = Use enable/disable pattern
Adds dc offset to the DAC Σ-∆ modulator to eliminate idle tones. It is
recommended
that this bit is disabled before the ADC/DAC engine is powered up
in
Control Register 0x0007[1].
0b = enabled
1b = disabled
