naibrd_ETC_GetElapsedTime()

NAIBRDFUNC nai_status_t NAIAPI naibrd_ETC_GetElapsedTime	(	int32_t	cardIndex,
		uint32_t *	outyear,
		uint32_t *	outday,
		uint32_t *	outhour,
		uint32_t *	outmin,
		uint32_t *	outsec )

Retrieves the Elapsed Time Counter (ETC) value in terms of year, day, hour, minutes and seconds.

Parameters

cardIndex	: (Input) Logical Card Index assigned to connection with the NAI_BOARD (0 - NAI_MAX_CARDS-1).
outyear	: (Output) ETC year.
outday	: (Output) ETC days within the year.
outhour	: (Output) ETC hours within the day.
outmin	: (Output) ETC minutes within the hour.
outsec	: (Output) ETC seconds within the minute.

Returns

• NAI_SUCCESS
• NAI_ERROR_INVALID_CARD when invalid card parameter is specified.

naibrd_ETC_GetTotalSeconds()

NAIBRDFUNC nai_status_t NAIAPI naibrd_ETC_GetTotalSeconds	(	int32_t	cardIndex,
		uint32_t *	outtotal_seconds )

Retrieves the Elapsed Time Counter (ETC) value in terms of total seconds.

Parameters

cardIndex	: (Input) Logical Card Index assigned to connection with the NAI_BOARD (0 - NAI_MAX_CARDS-1).
outtotal_seconds	: (Output) ETC total seconds.

Returns

• NAI_SUCCESS
• NAI_ERROR_INVALID_CARD when invalid card parameter is specified.

naibrd_ETC_Open()

NAIBRDFUNC nai_status_t NAIAPI naibrd_ETC_Open	(	int32_t	cardIndex,
		naibrd_comm_t	comm )

Opens access to the Elapsed Time Counter (ETC) in the SIU chassis based on the communication mode.

Parameters

cardIndex	: (Input) Logical Card Index assigned to connection with the NAI_BOARD (0 - NAI_MAX_CARDS-1).
comm	: (Input) Communications mode to use (currently only NAIBRD_COMM_I2C is supported).

Returns

• NAI_SUCCESS
• NAI_ERROR_INVALID_MODE when invalid communication mode parameter is specified.
• NAI_ERROR_INVALID_CARD when invalid card parameter is specified.
• NAI_ERROR_OPEN_FAILED when handle to board is invalid.
• NAI_NAI_ERROR_WRONG_DEVICE no ETC chip on the backplane.
