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.
PCM mode 0:
PCM mode 1:
PCM mode 2:
Offset Downstream bits 1…0, see POFD register.
Downstream Rising Edge.
0…the PCM-data is sampled with the falling edge of PDC
1…the PCM-data is sampled with the rising edge of PDC
Offset Upstream bits 1…0, see POFU register.
Upstream Rising Edge.
0…the PCM-data is transmitted with the falling edge of PDC
1…the PCM-data is transmitted with the rising edge of PDC
