Function Documentation

int gGTFEcmd (  gtemHandle  gt, unsigned short  temAddr, unsigned short  gtccAddr, unsigned short  gtrcAddr, unsigned short  gtfeAddr, unsigned short  opcode )

Sends a dataless command to the destination. Parameters: gt  gtemHandle for TEM temAddr  TEM address gtccAddr  GTCC address gtrcAddr  GTRC address gtfeAddr  GTFE address opcode  opcode of command to send Returns: G_OK on success

int gGTFEload (  gtemHandle  gt, unsigned short  temAddr, unsigned short  gtccAddr, unsigned short  gtrcAddr, unsigned short  gtfeAddr, unsigned short  reg, unsigned long long  value )

Loads a register with value. Parameters: gt  gtemHandle for TEM temAddr  TEM address gtccAddr  GTCC address gtrcAddr  GTRC address gtfeAddr  GTFE address reg  register of GTFE to load value  16-bit value to load into GTFE register Returns: G_OK on success Loads the GTFE register specified by reg with value

int gGTFEread (  gtemHandle  gt, unsigned short  temAddr, unsigned short  gtccAddr, unsigned short  gtrcAddr, unsigned short  gtfeAddr, unsigned short  reg, unsigned long long *  val )

Reads a register returing value in val. Parameters: gt  gtemHandle for TEM temAddr  temAddrination of command gtccAddr  GTCC address gtrcAddr  GTRC address gtfeAddr  GTFE address reg  register of GTFE to read val  pointer to storage to hold the response of the read command Returns: G_OK on success See also: _gGTFEread() Reads the GTFE register specified by reg. val is filled on return. The following error codes are returned when LATp errors occur: GERR_LATP_HEADER_PARITY GERR_LATP_CELL_PARITY GERR_LATP_TRUNCATE
