/* Switch for crossroad */
== Switch for crossroad ==
* the datasheet of the DSP implemented on the Explorer Board 16 (see pages 1 & , 278, 279) indicates that :
** output current of I/O : I_output = 10mA
** input current of I/O : I_output max = 5mA
** voltage I/O : VDD = 3.3V
** leakage current of I/O : 2uA
** low state ('0') in voltage : 0,2 * VDD
=== Formula ===
* voltage seens by the input of uC '''VDD_low''' when it's a low state : [math]VDD_{low} = VDD /cdot 0,2 =3.3 /cdot 0,2 [/math]
