Bit Number per PCM Frame.
PCM-mode 0: BNF7..0 = number of bits – 1
PCM-mode 1: BNF7..0 = (number of bits – 2) / 2
PCM-mode 2: BNF7..0 = (number of bits – 4) / 4
The value programmed in PBNR is also used to check the PFS period.
Offset Downstream bit 9…2.
These bits together with PCSR:OFD1..0 determine the offset of the PCM
frame in downstream direction. The following formulas apply for calculating
the required register value. BND is the bit number in downstream direction
marked by the rising internal PFS edge. BPF denotes the actual number of
bits constituting a frame.
PCM mode 0:
PCM mode 1:
PCM mode 2:
