int gPDUCcmd (  gdabHandle  gdab, unsigned short  pduAddr, unsigned short  opcode )

Sends a dataless command to the PDU. Parameters: gdab  gdabHandle containing the COM I/O (gnat) handle pduAddr  PDU address of command opcode  opcode of command to send Returns: G_OK on success Sends the dataless command specified by opcode to the PDU address specified by pduAddr.

int gPDUCload (  gdabHandle  gdab, unsigned short  pduAddr, unsigned short  reg, unsigned int  value )

Loads a register with value. Parameters: gdab  gdabHandle containing the COM I/O (gnat) handle pduAddr  PDU address of command reg  register to load value  32-bit value to load Returns: G_OK on success Loads the PDU Control register specified by reg with value

int gPDUCread (  gdabHandle  gdab, unsigned short  pduAddr, unsigned short  reg, unsigned int *  val )

Reads a register returing value in val. Parameters: gdab  gdabHandle containing the COM I/O (gant) handle. pduAddr  PDU address of command reg  register to read val  pointer t storage to hold the response of the read command Returns: G_OK on success Reads the PDU Control 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
