This application note describes a clock synchronous single master control module using Firmware Integration Technology (FIT), which uses clock synchronous serial communication over the quad serial peripheral interface (QSPI) on RX Family microcontrollers, and explains its use. SPI/QSPI mode single master control can be enabled by adding slave device selection control by means of port control. The QSPI FIT module implements single master basic control. Use the QSPI FIT module to create software for controlling slave devices.

AI 生成的摘要:
Audio playback of ADPCM data stored in NOR FLASH is achieved using the I2S master function on the RL78/G23 microcontroller. The system integrates NOR FLASH control via the Serial NOR Flash Memory Control Module Software Integration System (SIS) and uses M3S-S2-Tiny middleware for ADPCM encoding and decoding. The I2S communication supports PCM format with sampling frequencies of 8 kHz to 22.05 kHz and 16-bit data size. The document details hardware and software configurations, including pin usage, commands for writing and reading NOR FLASH, error handling, and flow charts for key functions. It also covers audio playback methods, middleware integration, and sample code for implementation.

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.

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.

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.
