naibrd_1553_RtAddrRelatch()

NAIBRDFUNC naibrd_1553_t NAIAPI naibrd_1553_RtAddrRelatch

(

int16_t

device

)

If RT_ADR_LAT is set high in the Misc Bits Auxiliary register (0x2), this function re-latches the RT address based on the current state of the external RT address pins. Use this function to make the device re-read the external RT address pins to reset the RT address of the device. If RT_ADR_LAT is set high, changing the state of the external pins by itself will not change the RT address of the device.

Parameters

device

: (Input) Logical Device Number (0-31).

Returns

• NAI_SUCCESS
• NAIBRD_1553_RC_INVALID_DEVICE_NUMBER when incorrect device number was input
• NAIBRD_1553_RC_INVALID_MODE when device is not set in RT or RT/MT mode
• NAIBRD_1553_RC_INVALID_STATE when device is in an invalid state

naibrd_1553_RtGetAddr()

NAIBRDFUNC naibrd_1553_t NAIAPI naibrd_1553_RtGetAddr	(	int16_t	device,
		naibrd_1553_rt_address_t *	p_outrtAddress )

Retrieves the RT address.

Parameters

device	: (Input) Logical Device Number (0-31).
p_outrtAddress	: (Output) Remote Terminal address assigned to the device (0-31).

Returns

• NAI_SUCCESS when the device has been initialized successfully
• NAIBRD_1553_RC_INVALID_DEVICE_NUMBER when incorrect device number was input
• NAIBRD_1553_RC_INVALID_MODE when device is not set in RT or RT/MT mode
• NAIBRD_1553_RC_INVALID_STATE when device is in an invalid state
• NAIBRD_1553_RC_INVALID_PARAMETER when p_outrtAddress pointer is null

naibrd_1553_RtGetAddrSrc()

NAIBRDFUNC naibrd_1553_t NAIAPI naibrd_1553_RtGetAddrSrc	(	int16_t	device,
		naibrd_1553_rt_rtAddressSource_t *	p_outrtAddressSource )

Gets RT address source (external or internal).

Parameters

device	: (Input) Logical Device Number (0-31).
p_outrtAddressSource	: (Output) Retrieved RT Address Source (NAIBRD_1553_RT_ADDR_SOURCE_INTERNAL, NAIBRD_1553_RT_ADDR_SOURCE_EXTERNAL).

Returns

• NAI_SUCCESS
• NAIBRD_1553_RC_INVALID_DEVICE_NUMBER when incorrect device number was input
• NAIBRD_1553_RC_INVALID_MODE when device is not set in RT or RT/MT mode
• NAIBRD_1553_RC_INVALID_STATE when device is in an invalid state
• NAIBRD_1553_RC_INVALID_PARAMETER when p_outrtAddressSource is null

naibrd_1553_RtSetAddr()

NAIBRDFUNC naibrd_1553_t NAIAPI naibrd_1553_RtSetAddr	(	int16_t	device,
		naibrd_1553_rt_address_t	rtAddress )

This function is used to set the RT address if the RT address source is set to Internal.

Parameters

device	: (Input) Logical Device Number (0-31).
rtAddress	: (Input) Remote Terminal address to be assigned to the device (0-31).

Returns

• NAI_SUCCESS when the device has been initialized successfully
• NAIBRD_1553_RC_INVALID_DEVICE_NUMBER when incorrect device number was input
• NAIBRD_1553_RC_INVALID_MODE when device is not set in RT or RT/MT mode
• NAIBRD_1553_RC_INVALID_STATE when device is in an invalid state
• NAIBRD_1553_RC_INVALID_PARAMETER when value of rtAddress is invalid
• NAIBRD_1553_RC_LIMITED_DEVICE when limited-performance device is not using RT 24
• NAIBRD_1553_RC_WRITE_ERROR when setting of the RT address failed

naibrd_1553_RtSetAddrSrc()

NAIBRDFUNC naibrd_1553_t NAIAPI naibrd_1553_RtSetAddrSrc	(	int16_t	device,
