The FRFORM 2 audio frame format is reserved.
12.6.4 FRFORM 3
shows the FRFORM 3 audio frame format. In this format, two
audio samples are transmitted per frame sync (FSYNC) cycle. FRFORM
3 uses a Left HIGH/Right LOW frame sync–that is, the Left sample is
present when FSYNC is HIGH, and the Right sample is present when
FSYNC is LOW. The FSYNC transition occurs at the first bit of each
sample. The transition of FSYNC from LOW-to-HIGH and HIGH-to-LOW
defines the beginning or end of each sample.
