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.

RX Family (FIT module)

The following software is a FIT module, i.e. within our FIT range, so it can easily be combined with other FIT modules. For example, transfer by a DMAC or DTC can easily be handled by combining this module with a DMAC or DTC module, both of which are currently available within our FIT range. (About FIT)
