Serial communications interface (SCI)
15.1 Introduction
15.1.1 Features
Features of SCI module include:
• Full-duplex, standard non-return-to-zero (NRZ) format
• Double-buffered transmitter and receiver with separate enables
• Programmable baud rates (13-bit modulo divider)
• Interrupt-driven or polled operation:
• Transmit data register empty and transmission complete
• Receive data register full
• Receive overrun, parity error, framing error, and noise error
• Idle receiver detect
• Active edge on receive pin
• Break detect supporting LIN
• Hardware parity generation and checking
• Programmable 8-bit or 9-bit character length
• Programmable 1-bit or 2-bit stop bits (SCI2 does not support 2-bit stop bits)
• Receiver wakeup by idle-line or address-mark
• Optional 13-bit break character generation / 11-bit break character detection
• Selectable transmitter output polarity
15.1.2 Modes of operation
See Section Functional description for details concerning SCI operation in these modes:
• 8- and 9-bit data modes
• Stop mode operation
