High-Speed Operation Problems with RSPI

Last Updated:06/08/2017


Communications do not operate properly when the RSPI bit rate is set to high speed. Where should I check to fix this?


You need to check the terminal setting used for RSPI. Check the setting of the “DSCR” drive capacity control register and select “High-drive output” for all the terminals which can be set to "high drive", and try again.

However, products that do not have the drive capacity control register "DSCR" are not included. (Target products: RX610 group, RX62T group, RX62G group)
