Chapter 5 Register Descriptions

which is described in Chapter 7, VXIplug&play

for the VXI-MXI-2. By default, the Transfer

Limit is set to Unlimited; with this setting, the

transfer count must not exceed 32 KB (8000 hex)

if the source of the DMA operation will use

synchronous MXIbus burst transfers. If you

changed the setting of the MXIbus Transfer

Limit control in the soft front panel to something

other than Unlimited, you must program the

transfer count to a multiple of the setting of the

Transfer Limit control. The only exception is

that you can also program the transfer count to

be smaller than the Transfer Limit control

setting. For example, assume the Transfer Limit

control in the soft front panel is set to 256. In this

case the transfer count must be programmed in

the range of 1 to 256 or set to one of 512, 768,

1024, and so on.
