This LSI is equipped with a 2-channel serial communication interface with built-in FIFO buffers

(Serial Communication Interface with FIFO: SCIF). The SCIF can perform both asynchronous and

clocked synchronous serial communications.

64-stage FIFO buffers are provided for both transmission and reception, enabling fast, efficient,

and continuous communication.

Channels 0 and 1 of the SCIF have modem control functions (RTS, CTS).

The SCIF has the following features.

• Asynchronous serial communication mode

• Clocked synchronous serial communication mode

Serial data communication is executed using an asynchronous system in which

synchronization is achieved character by character. Serial data communication can be carried

out with standard asynchronous communication chips such as a Universal Asynchronous

Receiver/Transmitter (UART) or Asynchronous Communication Interface Adapter (ACIA).

There is a choice of 8 serial data transfer formats.

 Data length: 7 or 8 bits

 Stop bit length: 1 or 2 bits

 Parity: Even/odd/none

 Receive error detection: Parity, framing, and overrun errors

 Break detection: A break is detected when a framing error lasts for more than 1 frame

Serial data communication is synchronized with a clock. Serial data communication can be

carried out with other LSIs that have a synchronous communication function.

There is a single serial data communication format.

 Data length: 8 bits

 Receive error detection: Overrun errors

length at Space 0 (low level). When a framing error occurs, a break can also be detected by

reading the SCIFn_RXD (n = 0, 1) pin level directly from the serial port register
