Data Structures
struct	ESM_NotifyParams
	Parameters used to register the ESM notify function to handle errors. The function will the invoked from the ISR of low or high priority ESM interrupt. More...
struct	ESM_OpenParams
	ESM Open Parameters. More...
struct	ESM_Object
	ESM Driver Object. More...
struct	ESM_GroupIntrStatus
	Structure to access the status of interrupts belonging to a High or Low priority interrupt. More...
struct	ESM_Attrs
	ESM Hardware Atrributes. More...
struct	ESM_Config
	ESM Instance configuration. More...

Macros
#define	ESM_MAX_NOTIFIERS   (4U)
	Maximum number of notify callbacks supported. More...
#define	ESM_MAX_ISR_COUNT   (4U)
	Maximum ISR supported. More...
#define	ESM_OPERATION_MODE_NORMAL   0x0U
	defines to select the ESM Operation Mode. More...
#define	ESM_OPERATION_MODE_ERROR_FORCE   0xAU
#define	ESM_INTRE_CONFIG_ERROR   (0x0u)
	Defines for ESM Hardware Requests for interrupt type. More...
#define	ESM_INTR_PRIORITY_LEVEL_LOW   (0x1u)
#define	ESM_INTR_PRIORITY_LEVEL_HIGH   (0x2u)

Typedefs
typedef void *	ESM_Handle
	A handle that is returned from a ESM_open() call. More...
typedef void(*	ESM_CallBack) (void *arg)
	Callback function which is invoked by the ESM module if a notify function is registered using the ESM_registerNotifier() API. More...

Functions
void	ESM_init (void)
	The functions initializes the ESM module. More...
void	ESM_deinit (void)
	The functions de-initializes the ESM module. More...
ESM_Handle	ESM_open (uint32_t index, ESM_OpenParams *params)
	Opens a ESM object with the index and parameters specified, and returns a ESM_Handle. More...
void	ESM_close (ESM_Handle handle)
	The function closes a ESM peripheral specified by the ESM handle. More...
int32_t	ESM_registerNotifier (ESM_Handle handle, ESM_NotifyParams *params)
	Register the notifers. The ESM module will call back if error interrupt is detected. More...
int32_t	ESM_deregisterNotifier (ESM_Handle handle, int32_t notifyIndex)
	Deregister the ESM notifers. More...
int32_t	ESM_setMode (uint32_t baseAddr, uint32_t mode)
	This API is used to configure operation mode of ESM module. More...
int32_t	ESM_setErrPinLowTimePreload (uint32_t baseAddr, uint32_t lowTime)
	This API is used to configure the low time counter pre-load value. More...
uint32_t	ESM_getCurrErrPinLowTimeCnt (uint32_t baseAddr)
	This API is used to read the low time counter pre-load value. More...
uint32_t	ESM_getErrPinStatus (uint32_t baseAddr)
	This API is used to get the current status of nERROR pin. More...
void	ESM_resetErrPin (uint32_t baseAddr)
	This API is used to reset the nERROR pin. More...
uint32_t	ESM_getIntrStatus (uint32_t baseAddr, uint32_t intrSrc)
	This API is used to get the interrupt status. More...
int32_t	ESM_getGroupIntrStatus (uint32_t baseAddr, uint32_t intrPrioType, ESM_GroupIntrStatus *pIntrstatus)
	This API is used to get the interrupt/error status for a group. This will also return highest pending interrupt for pulse as well as for level interrupts. More...
static void	ESM_Params_init (ESM_OpenParams *openPrms)

Variables
ESM_Config	gEsmConfig []
	Externally defined driver configuration array. More...
uint32_t	gEsmConfigNum
	Externally defined driver configuration array size. More...
