Detailed Description

Function Documentation

naibrd_AD_GetFIFOInterruptEnable()

NAIBRDFUNC nai_status_t NAIAPI naibrd_AD_GetFIFOInterruptEnable	(	int32_t	cardIndex,
		int32_t	module,
		int32_t	channel,
		nai_ad_fifo_status_t *	p_outmask )

Retrieves the A/D Interrupt Enable setting for the specified A/D channel's FIFO Buffer.

FIFO Buffer Interrupt Bit Format:
   (LSB) B0 - Empty        Interrupt when the A/D channel's FIFO counter is zero.
         B1 - Low Limit    Interrupt when the A/D channel's FIFO counter is less than or equal to the Low Threshold.
         B2 - High Limit   Interrupt when the A/D channel's FIFO counter is greater than or equal to the High Threshold.
         B3 - Full         Interrupt when the A/D channel's FIFO counter is equal to 26,213.
         B4 - Sample Done  Interrupt when the A/D channel's FIFO counter is equal to the FIFO size after the trigger occurs.
         B5 - Reserved
         B6 - Reserved
   (MSB) B7 - Reserved

Parameters

cardIndex	: (Input) Logical Card Index assigned to connection with the NAI_BOARD (0 - NAI_MAX_CARDS-1).
module	: (Input) Module Number of the module to access (1 - [max modules for board]).
channel	: (Input) Channel Number of the channel to access (1 - [max channels for module]).
p_outmask	: (Output) A/D FIFO Buffer Interrupt Enable Settings.

Returns

• NAI_SUCCESS
• NAI_ERROR_INVALID_CARD when invalid card parameter is specified.
• NAI_ERROR_INVALID_MODULE when invalid module parameter is specified.
• NAI_ERROR_NOT_OPEN when handle to board is invalid.
• NAI_ERROR_INVALID_CHANNEL when invalid channel parameter is specified.
• NAI_ERROR_NOT_SUPPORTED when function is not supported.
