Hi,

   

what is the drive strength in numbers???

   

 

   

typedef enum CyU3PDriveStrengthState_t
{
    CY_U3P_DS_QUARTER_STRENGTH = 0,     /* The drive strength is one-fourth the maximum */
    CY_U3P_DS_HALF_STRENGTH,            /* The drive strength is half the maximum */
    CY_U3P_DS_THREE_QUARTER_STRENGTH,   /* The drive strength is three-fourth the maximum */
    CY_U3P_DS_FULL_STRENGTH             /* The drive strength is the maximum */

} CyU3PDriveStrengthState_t;
 

   

How much mA or µA can a GPIO pin drive when it is configured to 1/4; 1/2; 3/4; 1 ???

   

thanks,
