Nucleo-F767ZI SPI config

[Sesha]

Hello,

I am practicing with nucleof767ZI. I have stuck with the SPI, here i am trying to send some dummy data and read it through an analyzer. What I get is MOSI always low and SCK is always high. I find no change or pulses in clock line. As of now nothing is connected to these pins. Code as follows,

void tempInit(void){
	RCC->CFGR = 0x0000D40A;
	RCC->AHB1ENR |= (1U << 0);//Enabling Port-A clock
	RCC->AHB1ENR |= (1U << 3);//Enabling Port-D clock
	RCC->APB2ENR |= (1U << 12);//Enabling SPI-1 clock
 
	GPIOA->MODER |= (0x10 << 5*2);//Port-A Pin- 5 SPI_SCK
	GPIOA->MODER |= (0x10 << 7*2);//Port-A Pin- 7 SPI_MOSI
	GPIOD->MODER |= (0x01 << 14*2);//Port-D Pin-14 SPI_SS
	GPIOA->AFR[0] = 0x50500000;
	GPIOA->AFR[1] = 0x00000000;
 
	SPI1->CR2 = 0x170C;
	SPI1->CR1 = 0xC33C;
 
	SPI1->CR1 |= 0x0040;
	SPI1_SS_Clear;
	while(1){
		SPI1->DR = 0x00AA;
	}
	SPI1->CR1 &= 0xFFBF;
}

This function is called directly from main after clock configuration. I know i am doing some mistake unable to find it out. Please help.

Thanks.

Sure you meant 0x10 here? And not 0b10? Same for the other two lines after it.

Thanks a lot TDK. I know i am doing a silly mistake, it needed a second eye to find it out. Solved.

Thanks again
