80
Description
(Non-object-oriented languages only)
Module identifier, returned by
PCport number (as if appears in the M3602A software)
Address that appears in the PCport interface
Number of 32-bit words to read (maximum is 128 words)
addressMode
Description
Auto
Initial address is incremented
Increment
after each access
Fixed
Initial address is used
for the whole access
accessMode
Description
Non-DMA
Memory access is split into multiple accesses
DMA
Memory access is done with a DMA transaction
(LabVIEW only) If it contains an error, the function will not be executed and errorIn will be
passed to errorOut
Rx data buffer
