int gGCCCcmd (  gtemHandle  gt, unsigned short  temAddr, unsigned short  gcccAddr, unsigned short  opcode )

Sends a dataless command to the TEM address. Parameters: gt  gtemHandle for TEM temAddr  TEM address of command gcccAddr  GCCC address opcode  opcode of command to send Returns: G_OK on success Sends the dataless command specified by opcode to the TEM address specified by temAddr.

int gGCCCload (  gtemHandle  gt, unsigned short  temAddr, unsigned short  gcccAddr, unsigned short  reg, unsigned int  value )

Loads a register with value. Parameters: gt  gtemHandle for TEM temAddr  TEM address of command gcccAddr  GCCC address reg  register of GCCC to load value  32-bit value to load into GCCC register Returns: G_OK on success Loads the GCCC register specified by reg with value

int gGCCCread (  gtemHandle  gt, unsigned short  temAddr, unsigned short  gcccAddr, unsigned short  reg, unsigned int *  val )

Reads a register returing value in val. Parameters: gt  gtemHandle for TEM temAddr  TEM address of command gcccAddr  GCCC address reg  register of GCCC to read val  pointer to storage to hold the response of the read command Returns: G_OK on success Reads the GCCC 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
