36+
// - The pins mentionned Px_y_ALTz are alternative possibilities which use other
37+
// HW peripheral instances. You can use them the same way as any other "normal"
38+
// pin (i.e. PwmOut pwm(PA_7_ALT0);). These pins are not displayed on the board
39+
// pinout image on mbed.org.
40+
//
41+
// - The pins which are connected to other components present on the board have
42+
// the comment "Connected to xxx". The pin function may not work properly in this
43+
// case. These pins may not be displayed on the board pinout image on mbed.org.
44+
// Please read the board reference manual and schematic for more information.
