unsigned short  temAddr,
unsigned short  gtccAddr,
unsigned short  gtrcAddr,
unsigned short  gtfeAddr,
unsigned short  reg,
unsigned long long  value
) 
 

Loads a register with value.

Parameters:
gt gtemHandle for TEM
temAddr TEM address
gtccAddr GTCC address
gtrcAddr GTRC address
gtfeAddr GTFE address
reg register of GTFE to load
value 16-bit value to load into GTFE register
Returns:
G_OK on success
Loads the GTFE register specified by reg with value

int gGTFEread (  gtemHandle  gt,
unsigned short  temAddr,
unsigned short  gtccAddr,
unsigned short  gtrcAddr,
unsigned short  gtfeAddr,
unsigned short  reg,
unsigned long long *  val
) 
 

Reads a register returing value in val.

Parameters:

gtfeAddr GTFE address
reg register of GTFE to read
val pointer to storage to hold the response of the read command
Returns:
G_OK on success
See also:
_gGTFEread()
Reads the GTFE 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
