int gGARCcmd (  gaemHandle  ga, unsigned short  garcAddr, unsigned short  opcode )

Sends a dataless command to the destination. Parameters: ga  gaemHandle for AEM garcAddr  GARC address opcode  opcode of command to send Returns: G_OK on success

int gGARCload (  gaemHandle  ga, unsigned short  garcAddr, unsigned short  reg, unsigned int  value )

Loads a register with value. Parameters: ga  gaemHandle for AEM garcAddr  GARC address reg  register of GARC to load value  16-bit value to load into GARC register Returns: G_OK on success Loads the GARC register specified by reg with value

int gGARCread (  gaemHandle  ga, unsigned short  garcAddr, unsigned short  reg, unsigned int *  val )

Reads a register returing value in val. Parameters: ga  gaemHandle for TEM garcAddr  GARC address reg  register of GARC to read val  pointer to storage to hold the response of the read command Returns: G_OK on success Reads the GARC 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
