Hello

I use TWR-K60D100M   spi0 is master , spi1 is slave ,  sip0 send "3" to spi1 ,  In the scope I can see the correct signal and clk singnal .

And I also can see the transfer count register " SPI1_TCR" work increase ,

And in the spi1 , I can see the spi1_sr_tcf  setting to 1, also spi1 can enter the receiving interrupt .

 

While in the FIFO register "SPI1_POPR" is always 0.  I don.t know why ?
