SPI/QSPI Serial Flash Memory, QSPI Serial Phase Change Memory Driver

Overview

This driver (sample program) uses the clock-synchronous serial I/O functions of a Renesas microcontroller to control reading, writing, and erasing of data.

RX Family
- Data can be read, written, and erased simply by calling user API functions.
- Control is possible using the following serial interfaces of the microcontroller:
- The clock-synchronous mode of the serial communication interface (SCI) and a single port are used for control.
- Clock-synchronous operation (three-wire) of the serial peripheral interface (RSPI) and a single port are used for control.
- The quad serial peripheral interface (QSPI) which is set to clock-synchronous operation and a single port are used for control.
RL78 Family, 78K Family
- Data can be read, written, and erased simply by calling user API functions.
- The SCI mode of the serial array unit (SAU) and a single port are used for control.
R8C Family, M16C Family
- Data can be read, written, and erased simply by calling user API functions.
- The clock-synchronous serial I/O function of the microcontroller and a single port are used for control.
