1. Will RL78F24 have the SPI Master sample code ?
2. Use RL78G23 sample code for Handshake-based SPI Master Transmission/Reception to porting to RL78F24. It can transfer SPI data and try to send one hex value. But some hex value is work , some hex value is fail . It seems the "low potential to high potential" become "high potential to low potential". Change the clock source ,baud rate, interface for SPI, the results are the same. Need your support.
example:
hex value :0x32 (ok)
hex value :0x31 (fail)
