Typedef Documentation

◆ EnetPer_Handle

typedef struct EnetPer_Obj_s* EnetPer_Handle

Ethernet Peripheral handle.

Ethernet Peripheral handle used to call any EnetPer related APIs.

◆ EnetPer_InitCfg

typedef void(* EnetPer_InitCfg) (EnetPer_Handle hPer, Enet_Type enetType, void *cfg, uint32_t cfgSize)

Initialize peripheral's configuration parameters.

Initializes the configuration parameter of the Enet Peripheral.

Parameters

hPer	Enet Peripheral handle
enetType	Enet Peripheral type
cfg	Configuration parameters to be initialized
cfgSize	Size of the configuration parameters

◆ EnetPer_Open

typedef int32_t(* EnetPer_Open) (EnetPer_Handle hPer, Enet_Type enetType, uint32_t instId, const void *cfg, uint32_t cfgSize)

Open and initialize the Enet Peripheral.

Opens and initializes the Enet Peripheral with the configuration parameters provided by the caller.

Parameters

hPer	Enet Peripheral handle
enetType	Enet Peripheral type
instId	Enet Peripheral instance id
cfg	Configuration parameters
cfgSize	Size of the configuration parameters

Returns: Enet_ErrorCodes

◆ EnetPer_Rejoin

typedef int32_t(* EnetPer_Rejoin) (EnetPer_Handle hPer, Enet_Type enetType, uint32_t instId)

Rejoin a running Enet Peripheral.

Reopens the Enet Peripheral, but doesn't perform any hardware initialization. This function is expected to be called to attach to a running peripheral.

This is an optional function and could be set to NULL if the peripheral doesn't implement it.

Parameters

hPer	Enet Peripheral handle
enetType	Enet Peripheral type
instId	Enet Peripheral instance id

Returns: Enet_ErrorCodes

◆ EnetPer_Ioctl

typedef int32_t(* EnetPer_Ioctl) (EnetPer_Handle hPer, uint32_t cmd, Enet_IoctlPrms *prms)

Issue an operation on the Enet Peripheral.

Issues a control operation on the Enet Peripheral.

Parameters

hPer	Enet Peripheral handle
cmd	IOCTL command Id
prms	IOCTL parameters

Returns: Enet_ErrorCodes

◆ EnetPer_Poll

typedef void(* EnetPer_Poll) (EnetPer_Handle hPer, Enet_Event evt, const void *arg, uint32_t argSize)

Poll for Ethernet events.

Unblocking poll for the events specified in evt.

This is an optional function and could be set to NULL if the peripheral doesn't implement it.

Parameters

hPer	Enet Peripheral handle
evt	Event type
arg	Pointer to the poll argument. This is specific to the poll event type
argSize	Size of `arg`

◆ EnetPer_ConvertTs

typedef uint64_t(* EnetPer_ConvertTs) (EnetPer_Handle hPer, uint64_t ts)

Convert a timestamp to nanoseconds.

Converts a peripheral-specific timestamp value to nanoseconds value. Timestamp values could be defined as bitfields or absolute values, so the peripheral has to perform the conversion to a nanosecond value, so it's presented in an uniform unit to the application.

This is an optional function and could be set to NULL if the peripheral doesn't implement it.

Parameters

hPer	Enet Peripheral handle
ts	Timestamp value, definition is peripheral specific

Returns: Nanoseconds value.

◆ EnetPer_PeriodicTick

typedef void(* EnetPer_PeriodicTick) (EnetPer_Handle hPer)

Run periodic tick on the Ethernet peripheral.

Run PHY periodic tick on the Ethernet peripheral.

hPer	Enet Peripheral handle

Register a callback for an event.

Registers a callback for an event. The callback will be called either via Enet_poll() when interrupts are disabled or internally by the driver when servicing an interrupt in ISR context.

Parameters

hPer	Enet Peripheral handle
evt	Event being registered for
evtNum	Event number. Use 0 for single event.
evtCb	Callback function
evtCbArgs	Callback function arguments

◆ EnetPer_UnregisterEventCb

Close the Enet Peripheral.

Closes the Enet Peripheral.

Parameters

hPer	Enet Peripheral handle
