Section 15 Serial Communication Interface (SCI, IrDA)

Either an internal clock generated by the on-chip baud rate generator or an external clock input at

the SCK pin can be selected as the SCI’s serial clock, according to the setting of the C/A bit in

SMR and the CKE1 and CKE0 bits in SCR. When an external clock is input at the SCK pin, the

clock frequency should be 16 times the bit rate used.

When the SCI is operated on an internal clock, the clock can be output from the SCK pin. The

frequency of the clock output in this case is equal to the bit rate, and the phase is such that the

rising edge of the clock is in the middle of the transmit data, as shown in figure 15.4.
