Where is "SPI3_SSEL"?
I'm trying to do SPI (1: N) with nucleo-F 446RE, but SPI 3 _ SSEL is not there. When I looked at the data sheet of MCU_LQFP 64 being used, it seems that it exists because there is SPI 3 _ NSS, but it was not in the image of the pasted pin arrangement somehow. Is this a mistake in the photo? Or does not it exist? Sorry for my poor English. Please answer.

It looks like there isn't a mistake in the photo, but rather the SPI3_SSEL is not pictured because it exists on an alternate pin
I found this information within the Mbed OS target
PeripheralPins.c file here: https://github.com/ARMmbed/mbed-os/blob/master/targets/TARGET_STM/TARGET_STM32F4/TARGET_STM32F446xE/TARGET_NUCLEO_F446RE/PeripheralPins.c#L286
You can view all of the valid pin names for the F446RE board here: https://github.com/ARMmbed/mbed-os/blob/master/targets/TARGET_STM/TARGET_STM32F4/TARGET_STM32F446xE/TARGET_NUCLEO_F446RE/PinNames.h
Please let me know if you have any questions!
