Function Documentation

static int __gcccCmdLoad (  gtemHandle  gt, unsigned short  temAddr, unsigned short  gcccAddr, unsigned short  func, unsigned short  reg, unsigned int  value )  [static]

Generic routine for sending response-less commands. Parameters: gt  gtemHandle for TEM temAddr  TEM address of command gcccAddr  GCCC address of command func  command/response function code reg  register of GCCC to load value  32-bit value to load into GCCC register Returns: G_OK on success Common subroutine for sending dataless commands and loading GCCC registers. The func parameter indicates a "dataless" or "load" command. For dataless commands reg is interpreted as the "opcode" of the dataless command and value is ignored. For load commands reg is the GCCC register to load with value.

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

void setCmdHeaderCAL (  gtemHandle  gt, cmdHeaderCAL *  ch, unsigned short  ext, unsigned short  gcccAddr, unsigned short  gcrcAddr )

initializes a command header structure for a GCCC Parameters: gt  gtemHandle for TEM ch  pointer to command header structure ext  set for "off board" commands, i.e. GCRC and GCFE commands gcccAddr  GCCC address gcrcAddr  GCRC address Returns: G_OK on void
