PCM-Offset Upstream Register (POFU)
Offset Upstream bit 9…2.
These bits together with PCSR:OFU1..0 determine the offset of the PCM-
frame in upstream direction. The following formulas apply for calculating the
required register value. BNU is the bit number in upstream direction marked
by the rising internal PFS-edge.
