Receive data sampling
The data received by the SSC2 is sampled after the latching edge of the input clock. The
latching edge being determined by the programming of the polarity and phase bits.
The data value which is finally latched is determined by taking three data samples at the
3rd, 4th and 5th system clock periods after the latching data edge. The data value is
determined from the predominant data value in the three samples. This therefore gives an
element of spike suppression.
The sampling process is shown in
