Audio Bit Manipulation
Overview
The tables in this appendix contain information on the manipulation of bits that occur when
using SFS6803
+
and OP
+
SFS
+
modules.
The following items are documented:
Manipulating Channel Status Bits (C-Bit)
Manipulating Validity and User Bits (V-Bit and U-Bit)
Identifying Audio Characteristics (Audio Sampling Frequency and Word
Length)
