-// =====
-// Px_y_ALTn pins are ALTernative possibilities which are not used per default.
-// You can use them as a normal pin name.
-// Example:
-// AnalogIn adc_in(PA_0_ALT0); // Use ADC_2 instead of ADC_1
-// =====
+//==============================================================================
+// Notes
+//
+// - The pins mentionned Px_y_ALTz are alternative possibilities which use other
+// HW peripheral instances. You can use them the same way as any other "normal"
+// pin (i.e. PwmOut pwm(PA_7_ALT0);). These pins are not displayed on the board
+// pinout image on mbed.org.
+//
+// - The pins which are connected to other components present on the board have
+// the comment "Connected to xxx". The pin function may not work properly in this
+// case. These pins may not be displayed on the board pinout image on mbed.org.
+// Please read the board reference manual and schematic for more information.
