• Description: Renesas 32-bit Risc Microcomputer Superh? Risc Engine Family
• Manufacturer: Renesas Electronics Corporation.

This LSI incorporates one channel of the Serial Protocol Interface (HSPI).
23.1
The HSPI has the following features.
• Operating mode: Master mode or Slave mode.
• The transmit and receive sections within the module are double buffered to allow duplex
• A flexible peripheral clock (Pck) division strategy allows a wide range of bit rates to be
• The programmable clock control logic allows setting for two different transmit protocols and
• Error detection logic is provided for warning of the receive buffer overflow.
• The HSPI has a facility to generate the chip select signal to slave modules when configured as
• Both the transmit data and receive data can be DMA transferred independently via the two
