Section 13 Serial Communication Interface
• Data length: 8 bits
• Receive error detection: overrun errors
• Full duplex communication
The transmitting and receiving sections are independent, so the SCI can transmit and receive
simultaneously. The transmitting and receiving sections are both double-buffered, so serial
data can be transmitted and received continuously.
• Built-in baud rate generator with selectable bit rates
• Selectable transmit/receive clock sources: internal clock from baud rate generator, or external
clock from the SCK pin.
• Four types of interrupts
Transmit-data-empty, transmit-end, receive-data-full, and receive-error interrupts are requested
independently. The transmit-data-empty and receive-data-full interrupts from SCI0 can
activate the DMA controller (DMAC) to transfer data.
