11. UART1 (SCI)
UART1 (SCI) is a general-purpose serial data communication interface for performing synchronous or asyn-
chronous communication (start-stop synchronization system). In addition to the normal duplex communication
function (normal mode), UART1 has a master-slave type communication function (multi-processor mode).
Data buffer: Full-duplex double buffer
Transfer mode: Clock synchronized (no start or stop bit)
Clock asynchronized (start-stop synchronization system)
Baud rate: With dedicated baud rate generator, selectable from 8 types
External clock input possible
Internal clock (a internal clock supplied from 16-bit reload timer can be used.)
Data length: 7 bits (for asynchronous normal mode only)
8 bits
Signal format: NRZ (Non Return to Zero) system
Reception error detection:Framing error
Overrun error
Parity error (not available in multi-processor mode)
Interrupt request: Receive interrupt (reception complete, receive error detection)
Receive interrupt (transmission complete)
Transmit/receive conforms to extended intelligent I/O service (EI2OS)
Master/slave type communication function (multi-processor mode):1 (master) to n (slave) communication pos-
sible (supported only for master station)
