Section 14 Serial Communication Interface (SCI)
• Asynchronous Mode
 Data length: Choice of 7 or 8 bits
 Choice of parity addition, multiprocessor bit addition, and addition of 1 or 2 stop bits (the
combination of these parameters determines the transmit/receive format and character
length)
 Detection of framing, parity, and overrun errors, receive FIFO data full and receive data
ready conditions, and breaks, during reception
 Detection of transmit FIFO data empty condition during transmission
 Choice of internal or external clock as SCI clock source
When internal clock is selected: The SCI operates on a clock with a frequency of 16, 8, or 4
times the bit rate of the baud rate generator, and can output this operating clock.
When external clock is selected: A clock with a frequency of 16, 8, or 4 times the bit rate
must be input (the built-in baud rate generator is not used).
• Synchronous Mode
 Transfer format: Fixed 8-bit data
 Detection of overrun errors during reception
 Choice of internal or external clock as SCI clock source
When internal clock is selected: The SCI operates on the baud rate generator clock and can
output a serial clock to external devices.
When external clock is selected: The on-chip baud rate generator is not used, and the SCI
operates on the input serial clock.
• IrDA Mode
 IrDA 1.0 compliance
 Data length: 8 bits
 Stop bit length: 1 bit
 Protection function to prevent receiver being affected during transmission
 Clock source: Internal clock
