Hi all Renesas Engineering Community,
I am using RL78/F15 in CS+ FOR CC
I want to use High-Speed DTC to transmit and receive data through CSI(Spi).
I read Hardware Manual and know that data can be get from the SDR register:
but when I config DCT, it can't take SDR register as source address
My question is: how to configure high speed DTC to receive and send data through CSI(Spi)?
Thank you!
Hello,
You need to skip the first hex value. For example for SDR11 the source address for DTC should be 0xFF4B.
Regards
Thank you for your answer,
I tried again and found that the source address must be from 0x0000 to 0x0fff
then you mean 0x0FF4 right?
You have selected a High Speed transfer. The high-speed transfer is realized by allocating the dedicated control data in the SFR area instead of the RAM area so the address range is smaller.
Please select Normal speed transfer and you will be able to set the address.
Thank you for your help, I can configure it now
