are inverted before being driven to a terminal; that is, these
signals are active low.
Note (NI PXIe-6386/6396 Devices) PXIe-6386 and PXIe-6396 devices differ in
several ways from other SMIO devices. For more information about sample clock

Using PFI Terminals as Static Digital I/Os
Each PFI can be individually configured as a static digital input or a static digital output. When
a terminal is used as a static digital input or output, it is called P1.x or P2.x. On the I/O connector,
each terminal is labeled PFI x/P1.x or PFI x/P2.x.
In addition, X Series devices have up to 32 lines of bidirectional DIO signals.
