• Manufacturer Part Number: H8S2110B
• Description: Renesas 16-Bit Single-Chip Microcomputer Renesas H8S Family/H8S/2100 Series
• Manufacturer: RENESAS [Renesas Technology Corp]

This LSI has a serial communication interface (SCI). The SCI can handle both asynchronous and
clocked synchronous serial communication. Asynchronous 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
function is also provided for serial communication between processors (multiprocessor
communication function) in asynchronous mode.
12.1
Asynchronous Mode:
SCI0022C_000020020800
Choice of asynchronous or clocked synchronous serial communication mode
Full-duplex communication capability
The transmitter and receiver are mutually independent, enabling transmission and reception to
be executed simultaneously. Double-buffering is used in both the transmitter and the receiver,
enabling continuous transmission and continuous reception of serial data.
The on-chip baud rate generator allows any bit rate to be selected
An external clock can be selected as a transfer clock source.
Choice of LSB-first or MSB-first transfer (except in the case of asynchronous mode 7-bit data)
Four interrupt sources
Four interrupt sources — transmit-end, transmit-data-empty, receive-data-full, and receive
error — that can issue requests.
Data length: 7 or 8 bits
Stop bit length: 1 or 2 bits
Parity: Even, odd, or none
Receive error detection: Parity, overrun, and framing errors
Break detection: Break can be detected by reading the RxD pin level directly in case of a
framing error
