 Synchronous mode
Serial data communication is synchronized with a clock. In his mode, serial data can be
exchanged with another LSI that has a synchronous communication function.
Data length 8 bits
Receive error detection Overrun errors
• Full-duplex communication
Separate transmission and reception units are provided, enabling transmission and reception to
be carried out simultaneously. The transmission and reception units are both double-buffered,
allowing continuous transmission and reception.
• On-chip baud rate generator, allowing any desired bit rate to be selected
• Choice of an internal or external clock as the transmit/receive clock source
• Six interrupt sources: transmit end, transmit data empty, receive data full, overrun error,
framing error, and parity error
