Transfer mode

The transfer mode depends on the device. The current version does not support BusMaster and DMA.

 

It is a mode that all communications use interrupt to communicate.

It is a mode that data transfer between the GPIB board and memory is done by direct memory access but not handled directly by the CPU.

It is a mode that data transfer uses on-board FIFO memory.

In DMA mode, memory access uses on-PC DMA controller, whereas, in BusMaster mode, memory access uses on-board MDA controller.
