Bit Name Description
PRE_C[15:8]
Eight most significant bits of the 16-bit Preamble-C, when nonaudio data is detected according to the IEC60937
standard; otherwise, bits show zeros.

Bit Name Description
PRE_D[15:8]
Eight most significant bits of the 16-bit Preamble-D, when nonaudio data is detected according to the IEC60937
standard; otherwise, bits show zeros. When subframe nonaudio is used, this becomes the eight most significant bits
of the 16-bit Preamble-C of Channel B.
