Section 13 Serial Communication Interface
Restrictions on Usage of the Serial Clock
When transmitting data using an external clock as the serial clock, an interval of at least 5 states is
necessary between clearing the TDRE bit in SSR and the start (falling edge) of the first transmit
clock pulse corresponding to each frame (see figure 13.22). This condition is also needed for
continuous transmission. If it is not fulfilled, operational error will occur.
