TM4C123GH6PM: SSI1 and above are not working !!! on my TIVA C

Simply, I'm trying to Interface nrf24l01+ (Wireless module) module through SSI0 (SPI), and it works perfectly. on PINS (PA 2 PA3 PA4 PA5)

When I try to switch to a different SSIn, for example, use SSI1 (SPI) on PINs (PD0 PD1 PD2 PD3) It never works?!!

Am I missing something special for SSIx which is not required for SSI0?

The following is the code related to the initialization of the SSIx I'm using for both cases 0 and 1

if(SSI_BASE == SSI0_BASE){
		SysCtlPeripheralEnable(SYSCTL_PERIPH_SSI0);
		SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOA);

		GPIOPinConfigure(GPIO_PA2_SSI0CLK);
		// The following PIN is for CS, any PIN may be used since we're Master
		GPIOPinTypeGPIOOutput(GPIO_PORTA_BASE, GPIO_PIN_3);
		GPIOPinWrite(GPIO_PORTA_BASE, GPIO_PIN_3, GPIO_PIN_3);
		// end of CS code
		GPIOPinConfigure(GPIO_PA4_SSI0RX);
		GPIOPinConfigure(GPIO_PA5_SSI0TX);
		GPIOPinTypeSSI(GPIO_PORTA_BASE, GPIO_PIN_5|GPIO_PIN_4|GPIO_PIN_2);
	}else if(SSI_BASE == SSI1_BASE){
	    SysCtlPeripheralEnable(SYSCTL_PERIPH_SSI1);
	    SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOD);

        GPIOPinConfigure(GPIO_PD0_SSI1CLK);
        // The following PIN is for CS, any pin may be used since we're Master
        GPIOPinTypeGPIOOutput(GPIO_PORTD_BASE, GPIO_PIN_1);
        GPIOPinWrite(GPIO_PORTD_BASE, GPIO_PIN_1, GPIO_PIN_1);
        // end of CS code
        GPIOPinConfigure(GPIO_PD2_SSI1RX);
        GPIOPinConfigure(GPIO_PD3_SSI1TX);
        GPIOPinTypeSSI(GPIO_PORTD_BASE, GPIO_PIN_3|GPIO_PIN_2|GPIO_PIN_0);
	}
