• Manufacturer Part Number: HD6417615
• Description: Hardware Manual
• Manufacturer: Hitachi Semiconductor

14.1
The SH7615 is equipped with a two-channel serial communication interface with built-in FIFO
buffers (SCIF: SCI with FIFO). The SCIF can handle both asynchronous and synchronous serial
communication. A function is also provided for serial communication between processors
(multiprocessor communication function).
An on-chip Infrared Data Association (IrDA) interface based on the IrDA 1.0 system is also
provided, enabling infrared communication.
Sixteen-stage FIFO registers are provided for both transmission and reception, enabling fast,
efficient, and continuous communication.
14.1.1
The SCIF has the following features:
Choice of synchronous or asynchronous serial communication mode
Section 14 Serial Communication Interface with FIFO
Asynchronous 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). A multiprocessor communication function is also provided that enables
serial data communication with a number of processors.
There is a choice of 12 serial data communication formats.
