Characteristic
Description
Default Value
Slave DMA Channel
This indicates the slave DMA channel to be
used in all slave accesses to the VXI Shared
RAM in A24 space or the PC I/O in A16 space.
This value must correspond to jumper settings
on the AT-MXI board. You can select the
NONE option with any jumper settings.
Range = 0, 1, 2, 3, 5, 6, 7, 0xff (NONE)
Note: If you select the NONE option, slave
accesses to VXI Shared RAM and to PC I/O
space will not succeed. Accesses to VXI-
defined registers on the AT-MXI board,
however, remain unaffected.
