Section 15 Serial Communication Interface (SCI)
15.4
15.4.1
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 or clock synchronous mode is selected and the transmit format is specified in the
serial mode register (SCSMR) as shown in table 15.13. The SCI clock source is selected by the
combination of the C/A bit in SCSMR and the CKE1 and CKE0 bits in the serial control register
(SCSCR) as shown in table 15.14.
(1)
• Data length is selectable: 7 or 8 bits.
• Parity bit is selectable. So is the stop bit length (1 or 2 bits). The combination of the preceding
• 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.
(2)
• The transmission/reception format has a fixed 8-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.
