3 Keysight SD1 Command Reference
3. 3. 4 SD_Module Functions (M3602A FPGA-related)
The FPGAwritePCport and FPGAreadPCport functions are related to the [4] Keysight
M3602A FPGA Design Environment Software on page 85 .
3. 3. 4. 1 FPGAwritePCport
Writes data at the PCport FPGA block (Option FP1 required).
Parameters
Name Description
Inputs
moduleID (Non-object-oriented languages only) Module identifier, returned by open on page 28
nPCport PC port number
data Data buffer to write through PC port to FPGA
dataSize Number of 32-bit words to write (maximum is 128 words)
address Address that appears in the PCport interface
addressMode Selects between the two address modes shown below:
addressMode Description Name Value
Auto
Increment Initial address is incremented
after each access ADDRESSING_AUTOINCREMENT 0
Fixed Initial address is used
for the whole access ADDRESSING_FIXED 1
accessMode Selects between the two memory access modes shown below:
accessMode Description Name Value
Non-DMA Memory access is split into multiple accesses NONDMA 0
DMA Memory access is done with a DMA transaction DMA 1
errorIn (LabVIEW only) If it contains an error, the function will not be executed and errorIn will be
passed to errorOut
Outputs
moduleIDout (LabVIEW only) A copy of moduleID
errorOut See Error Codes on page 83
