DRA register is used to attenuate the level of
audio output at the Right Channel using the but-
terfly shown in Fig. 11. When the register is set to

A decimal unit correspond to an attenuation step
of 1 dB.
Default value is 0x00, corresponding at the maxi-
mum attenuation in the re-direction channel.
The VCO output frequency, when decoding
44.1KHz bitstream, is divided by (MFSDF_441 +1)
