Section 12 Serial Communication Interface (SCI)
Data Transfer Format
A fixed 8-bit data format is used.
No parity or multiprocessor bits are added.
Clock
Either an internal clock generated by the built-in baud rate generator or an external serial clock
input at the SCK pin can be selected, according to the setting of the C/A bit in SMR and the CKE1
and CKE0 bits in SCR. For details of SCI clock source selection, see table 12.9.
When the SCI is operated on an internal clock, the serial clock is output from the SCK pin.
Eight serial clock pulses are output in the transfer of one character, and when no transfer is
performed the clock is fixed high. When only receive operations are performed, however, the
serial clock is output until an overrun error occurs or the RE bit is cleared to 0. To perform receive
operations in units of one character, an external clock should be selected as the clock source.
