17.3.1
For serial communication, the SCI has an asynchronous mode in which characters are
synchronized individually, and a clock synchronous mode in which communication is
synchronized with clock pulses.
Asynchronous/clock synchronous mode and the transmission format are selected in the serial
mode register (SCSMR), as listed in table 17.9. The SCI clock source is selected by the
combination of the C/A bit in the serial mode register (SCSMR) and the CKE1 and CKE0 bits in
the serial control register (SCSCR), as listed in table 17.10.
Asynchronous Mode:
• Data length is selectable: seven or eight bits.
• Parity and multiprocessor bits are selectable. So is the stop bit length (one or two bits). The
• In receiving, it is possible to detect framing errors, parity errors, overrun errors and breaks.
• An internal or external clock can be selected as the SCI clock source.
Clock Synchronous Mode:
• The transmission/reception format has a fixed eight-bit data length.
• In receiving, it is possible to detect overrun errors.
• An internal or external clock can be selected as the SCI clock source.
combination of the preceding selections constitutes the communication format and character
length.
⎯ When an internal clock is selected, the SCI operates using the on-chip baud rate generator,
⎯ When an external clock is selected, the external clock input must have a frequency 16 times
⎯ When an internal clock is selected, the SCI operates using the on-chip baud rate generator,
