Now i am using the spi1 to do some communication work, and i set the spi as master, 3 pin mode. but when i set the dataformat to 3 it can't change the clk's prescale by the function "SPIClkConfigure(unsigned int baseAdd, unsigned int moduleClk,unsigned int spiClk, unsigned int dataFormat)", if i set the dataformat to 0 ,it can be changed by this function." why this happen? And by the manual it is said that under the slave mode it should just can use dataformat0, but i have set it to master mode, why i still can't change the clk?
