• Parity: Even, odd, or none
• Receive error detection: Parity, overrun, and framing errors
• Break detection: Break can be detected by reading the RxD pin level directly in the case of a
framing error
• Average transfer rate generator (SCI_0): 720 kbps, 460.784 kbps, or 115.192 kbps can be
selected at 16-MHz operation (H8S/2239 Group only).
• Transfer rate clock can be input from the TPU (SCI_0) (H8S/2239 Group only).
• Communications between multi-processors are possible.
Clocked Synchronous mode
• Data length: 8 bits
• Receive error detection: Overrun errors detected
• SCI selection (SCI_0) : When IRQ7 = 1, fixed input of TxD0 = Hi-Z and SCK0 = High can be
selected. (H8S/2239 Group only)
Smart Card Interface
• Automatic transmission of error signal (parity error) in receive mode
• Error signal detection and automatic data retransmission in transmit mode
• Direct convention and inverse convention both supported
