19.3.1
For serial communication, the SCIF has an asynchronous mode in which characters are
synchronized individually. Refer to section 17.3.2, Operation in Asynchronous Mode. The SCIF
has the 16-byte FIFO buffer for both transmit and receive, reduces an overhead of the CPU, and
enables continuous high-speed communication. Moreover, it has the RTS2 and CTS2 signals as
the modem control signals. The transmission format is selected in the serial mode register 2
(SCSMR2), as listed in table 19.6. The clock source of SCIF is determined by the combination of
CKE1 and CKE0 bits in the serial control register 2 (SCSCR2) as shown in table 19.7.
• Data length is selectable from 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 (FER), parity errors (PER), receive FIFO
• In transmitting, it is possible to detect transmit FIFO data empty.
• The number of stored data for both the transmit and receive FIFO registers is displayed.
• SCIF clock source

⎯ The SCIF operates using the on-chip baud rate generator, and can output a serial clock
signal with a frequency 16 times the bit rate.
