PRELIMINARY
6.7.3
The bit shift is performed on half-bit steps, not on a clock basis. It is a true bit shift, it
means that with a data rate equals to the data clock frequency (e.g. 4.096 Mbit/s with
4.096 MHz data clock) programming a bit shift of 1-bit results on a shift of 1 clock period,
and programming a shift of half-bit the result is a shift of half clock period. Running in
double data clock rate (e.g. 4.096 Mbit/s with 8.192 MHz data clock), a bit shift of 1-bit
results on a shift of 2 clock periods and a shift of half-bit will result on a shift of 1 clock
period.

Example (8-bit µP interface):
Begin time-slot 0 of local input line 8 with the 4th rising edge relative to one byte before
the PFS rising edge. The bits are internally sampled with the falling edge.
