Note: Some pins offer multiple GPIO alternate function configuration, while others do not. For example, for LED1 (PB10), it is possible to drive the intensity of the LED through a regular GPIO function or through the PWMA function multiplexed on this pin. However, for TOUCH_Y7 (PB12), if the GPIO function configuration is different than CAT.CSA[15], the touch interface of this board won't be functional.
