Serial data sent by the transmitter may be synchronized with either the trailing (HIGH-to-LOW) or the
leading (LOW-to-HIGH) edge of the clock signal. However, the serial data must be latched into the
receiver on the leading edge of the serial clock signal, and so there are some restrictions when
transmitting data that is synchronized with the leading edge (see figure below ).
Note that the specifications are defined by the transmitter speed. The specification of the receiver has to be able
to match the performance of the transmitter.
