Function Documentation

int fwSpecs_JTAGDRScan	(	string	pSPECS,
		int	pMasterID,
		int	pSlaveAddress,
		int	pBus,
		int	pSize,
		dyn_char	pDataIn,
		dyn_char &	pDataOut
	)

Perform a DR SCAN operation in the specified JTAG.

Parameters:

[in]	pSPECS	name of the SPECS.
[in]	pMasterID	master ID.
[in]	pSlaveAddress	slave address.
[in]	pBus	bus number.
[in]	pSize	size (in bits) of the data to be shifted in.
[in]	pDataIn	data to be shifted in.
[out]	pDataOut	data that has been shifted out.

Returns:

= 0 no error found.

> 0 error found (related with SpecsUser; see error codes).

= -1 error found (related with PVSS).

Example:

  (...)
  dyn_char myData;

  if (fwSpecs_JTAGDRScan("pclbcecs03", 1, 1, 0, 24, makeDynChar(65, 66, 67), myData) == 0)   // perform a DR SCAN operation
     DebugTN(myData);
  else
     DebugTN("Error found!");
  (...)

int fwSpecs_JTAGIdle	(	string	pSPECS,
		int	pMasterID,

Parameters:

[in]	pSPECS	name of the SPECS.
[in]	pMasterID	master ID.
[in]	pSlaveAddress	slave address.
[in]	pBus	bus number.

Returns:

= 0 no error found.

> 0 error found (related with SpecsUser; see error codes).

= -1 error found (related with PVSS).

Example:

  (...)
  if (fwSpecs_JTAGIdle("pclbcecs03", 1, 1, 0) == 0)   // perform a IDLE operation

[in]	pBus	bus number.
[in]	pSize	size (in bits) of the data to be shifted in.
[in]	pDataIn	data to be shifted in.
[out]	pDataOut	data that has been shifted out.

Returns:

= 0 no error found.

= -1 error found (related with PVSS).

Example:

  (...)
  dyn_char myData;

  if (fwSpecs_JTAGIRScan("pclbcecs03", 1, 1, 0, 24, makeDynChar(65, 66, 67), myData) == 0)   // perform a IR SCAN operation
