rx-231 SCI6 as SPI

Hello Rachmat,

SCI6 can be used  for SPI communication, but can you please define the model of the external RAM that you want to use?

Hello

RAM typr is LY68L6400SLIT

Hello Rachmat,

Unfortunately. the LY68L6400SLIT is a SPI/QSPI PSRAM device and there isn't any available sample code for this kind of memories on RX231.

The only that I found is the below:

https://www.renesas.cn/cn/zh/document/apn/rx-family-clock-synchronous-control-module-serial-nor-flash-memory-access-firmware-integration

which implements SPI communication for SPI/QSPI FLASH memories and its seems that it uses RSPI peripheral for RX231 device:

Ιt seems that you will need to design the SPI SCI6 from scratch following the LY68L6400SLIT's user's manual.

I will ask more information internally, but it seems difficult to find something that matches with your request.

I will inform you for any news.
