(AI-64XE-10), and PCI-6071E (MIO-64E-1), you also must call MIO_Config if you plan
touse AMUX -64T channels. Refer to the MIO_Config function for further details.
Note Some of the digital lines of port 0 on the MIO or AI device with AMUX-64T
devices are reserved for AMUX device control. Any attempt to change the port or
line direction or the digital values of the reserved line causes an error. Table2-2
shows the relationship between the number of AMUX-64T devices assigned to the
MIO or AI device and the number of digital I/O lines reserved. You can use the
remaining lines of port 0. On non-E Series devices, the remaining lines are
available for output only.
