Function Documentation

int gGCRCcmd (  gtemHandle  gt, unsigned short  temAddr, unsigned short  gcccAddr, unsigned short  gcrcAddr, unsigned short  opcode )

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

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

Loads a register with value. Parameters: gt  gtemHandle for TEM temAddr  TEM address gcccAddr  GCCC address gcrcAddr  GCRC address reg  register of GCRC to load value  16-bit value to load into GCRC register Returns: G_OK on success Loads the GCRC register specified by reg with value

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

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