Confirmation on SPI port configuration in STM32F207VET6

Hi,

We are using STM32F207VET6 microcontroller.

We are requiring 2 SPI ports for different peripherals. Some SPI port pins are captured by ethernet, JTAG etc.so I can not use them. 

Following SPI signals I have configured on port pins. Please confirm if this is correct way. 1 signal of SPI1 is configured on other port. I want to confirm whether I can use 3 SPI signal in 1 port and 1 in another port.

SPI1_NSS --> PA4

SPI1_SCK 

--> PA5

SPI1_MISO--> PA6

SPI1_MOSI--> PB5    (SPI1_MOSI is configured on port B, and other signals are configured on port A)

SPI3_NSS --> PC9

SPI3_SCK 

--> PC10

SPI3_MISO--> PC11

SPI3_MISO--> PC12

Please confirm me on above connection 

Thanks

Satish

SPI1_MOSI--> PB5 (SPI1_MOSI is configured on port B, and other signals are configured on port A)

-> This configuration is allowed and correct.

For the SPI3, the PC9 pinshould be configured as GPIO output.

Khouloud.
