Other value means it's not same, it is changing every time.I'm checking the TXCRCR register in the debug mode,after line 3, TXCRCR will become 0x0000.after line 4, TXCRCR register should be 0x0000 - is my understanding right?after line 5, TXCRCR regi...

@waclawek.jan and @Tesla DeLorean ,thank you for reply,Here is my code,Initialization:RCC->APB2ENR |= (1<<12); //Enable SPI1 ClockSPI1->CR1 |= (1<<11); // DFF=1, 16 bit dataSPI1->CR1 |= (1<<0); // CPHA=1SPI1->CR1 &= ~(1<<1); //CPOL=0SPI1->CR1 |= (1<<...
