4.2.11 Event Management API – Available with all 73S12xxF Devices
The Event Management API allows the application to handle all system events. An application should
always call Events_Init() to initialize all event vectors at the beginning of the main program. The API
includes:
• Events_Init() (page 55)
• Events_Clear() (page 55)
• Get_Event () (page 56)
• Set_Event () (page 56)
Events_Init()
Purpose Initialize the system default event vectors. Upon exiting this function, all vectors will
point to a null_isr. For this reason, every feature (Smart card, USB, RTC, Keypad,
LCD, etc.) must call its initialization routine so that its interrupt service routine will be
set properly.
Synopsis void Events_Init ( void );
Parameters None.
Return Codes None.
Events_Clear()
Purpose Clear selected events.
Synopsis Void Events_Clear ( unsigned long Events );
Parameters Events: Input parameter
