Number of elements the destination offset is incremented after every transfer.
This value can be 0 or 1. The default value is 1.
Because the default value of this property is 1, the destination address is incremented
after each transfer, and the MoveOut methods write into consecutive elements. If you set
this property to 0, the MoveOut methods always write to the same element, essentially
treating the destination as a FIFO register.
For MoveIn methods, specifies whether to do a block move or a FIFO read.
Number of elements the source offset is incremented after every transfer.
This value can be 0 or 1. The default value is 1.
Because the default value of this property is 1, the source address is incremented
after each transfer, and the MoveIn methods read from consecutive elements. If you set
this property to 0, the MoveIn methods always read from the same element, essentially
treating the source as a FIFO register.
Occurs when a VXIbus interrupt is received from the device.
Occurs when a VXIbus signal or VXIbus interrupt is received from the device.
Occurs when a VXIbus trigger is received from the device.
Occurs when a service request is received from the device.
When this event is received, client code should call ReadStatusByte.
