SPC5744 support SPI frame 24bit

[williamliu]

如下图SPC5744支持SPI 通讯24bit的，但是官方提供的参考程序只有16bit的，目前16bit可以正常通讯，但是现在需要用24bit frame，根据手册的上的寄存器配置不成功。请问是否有相关的参考程序？

Hi,

as mentioned in the text, you should use continuous selection format, for more info refer to chapter 49.4.4.5 Continuous Selection Format of the device Reference Manual.

So configure 8 bits transfers and send 3 bytes with chip select asserted between transfers.
