CHIP_SCT_EVENT wrong definition

Hi,

I think there is a small bug in the lpcOpen library for the LPC 43xx chips. The following definition:

typedef enum CHIP_SCT_EVENT {
   SCT_EVT_0 = (1 << 0),   /*!< Event 0 */
   SCT_EVT_1 = (1 << 1),   /*!< Event 1 */
   SCT_EVT_2 = (1 << 2),   /*!< Event 2 */
   SCT_EVT_3 = (1 << 3),   /*!< Event 3 */
   SCT_EVT_4 = (1 << 4)   /*!< Event 4 */
} CHIP_SCT_EVENT_T;

does not match with the specification of the models LPC 43xx, as long as these models have 16 Events (Ev0.. Ev15).

As consequence, if I use a method like:

void Chip_SCT_DisableEventInt(LPC_SCT_T *pSCT, CHIP_SCT_EVENT_T evt)

I get the following warning and a not correct behavior if the event is greater than 4:

warning: large integer implicitly truncated to unsigned type [-Woverflow]

Regards.

Hi Javier Vallori，

Thanks for your reporting, I'll contact with AE team about the enum value.

Thanks again.
Have a great day,
