• 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
Note: On the H8/38124 Group, the system clock generator must be used when carrying out this
function.
