Coarse Step Size
: The step size of the gain that is to be indicated over the LSBs. The possible step sizes
are 0dB, 1dB, 2dB, 3dB, 4dB, 5dB, 6dB, 8dB.
Number of Bits for Coarse Index
: Number of bits that are to be used to indicate the coarse gain value.
Possible values for this operand can be: 0,2,3,4. But this value also depends on the ALC mode that is
being operated in.
Coarse Index Invert
: Applicable in only modes where coarse index is sent on the LSBs. If 0, send the
coarse index. If 1, all the bits of coarse index are flipped and sent.
