R1EX25032A

AI-generated Summary: The software controls clock synchronous communication using the 3-wire serial I/O (CSI mode) of the RL78 microcontroller's serial array unit as a single master. It supports MSB-first transfer and CPU-driven data transfer but lacks chip-select control and DMA or interrupt-driven transfer. The software operates under specified conditions with RL78/G14 and Renesas R1EX25xxx SPI EEPROM, using CS+ development environments and standard compiler settings.

AI-generated Summary: The SCIFA FIT module enables easy integration of clock synchronous single master control into RX Family microcontrollers through APIs. It supports initialization, control, transmit/receive, interrupt handling, and error logging functions. Operation is confirmed on RX64M and RX71M groups with specified memory sizes, compiler settings, and development environments. Memory requirements vary by compiler version and endian mode.

AI-generated Summary: The document details a sample program for RX family microcontrollers using RSPI for clock synchronous single master control via a three-wire serial communication method. It supports single-channel operation with MSB-first data transfer in both big and little endian formats. The code excludes chip select control and DMA transfers and allows normal or high-speed receive modes. Supervisor mode operation is required for high-speed mode, while normal mode supports both user and supervisor modes. The RSPI module's features and peripheral usage are outlined, including port requirements for slave device selection.

AI-generated Summary: The document details control software for Renesas R1EX24xxx series serial EEPROMs using Renesas MCUs. It explains communication protocols including write, acknowledge polling, and read operations via I2C single master control software. The software supports multiple channels and slave devices, handles address conversion based on EEPROM capacity, and includes recovery functions for bus errors. It also outlines peripheral functions and usage examples for serial EEPROM communication.

AI-generated Summary: The document details the Renesas R1EX25xxx Series Serial EEPROM control software for RX, RL78, and 78KOR/Kx3-L MCU families. It describes driver initialization, read/write processes, command handling, and internal functions. The software manages SPI Serial EEPROM devices via MCU's synchronous serial communication, supporting up to two devices with configurable communication speed and endian modes. Evaluation conditions for RX610 MCU include operating frequency, voltage, development environment, and compiler settings.

AI-generated Summary: This document details the implementation of clock synchronous single master control using the SCI interface on RX family microcontrollers. It supports SPI mode with software-based MSB-first data transfer and both big and little endian formats. The sample code handles single master transmit, receive, and transmit/receive operations using CPU transfers only, without support for DMAC, EXDMAC, DTC, or interrupt-driven transfers. Chip select control is not included and must be implemented separately if needed.
