2) With RDS = 1 the sampling edge is shifted 1/2 clock phase forward. The data
before HDC falling edge). In this case TxDB becomes invalid again, TSCB is
set to inactive ‘1’, and the internal counters are not incremented, so the same
valid data will be shifted out again with the next HDC/HFS rising edge.
is internally still processed with the falling edge. Therefore the strobe timing is
still related to the next falling edge in that case.
