THE VX PINS AS DIGITAL INPUTS
VX1-5 have dual functionality. As analog inputs, they can be
programmed as described above. The only difference to the VP/VH
inputs is that there is only one range to be selected and offer a true
high impedance input.
VX1-5 can also be programmed as digital inputs and these digital
inputs are CMOS/TTL compatible. The features of the inputs in this
mode are as follows:-
Programming of VX1-5 is in digital mode is shown below.
Figure 41. Programming a VX pin in digital mode
When used in digital mode, the analog detector circuit, although
disconnected from the VX input pin, is still available for use. The
circuit can be mapped to one of the other inputs to provide a second
detector on that pin. VX1 is mapped to VP1, VX2 is mapped to VP2
etc. VX5 is mapped to VH. (The text as indicated in figure 42 helps
the user with this process). This allows the user to set up an
ALARM and FAULT window on a supply without using up extra

Can be programmed to detect either a level or an edge
Can be programmed to respond on either a rising or falling
level/edge
A weak pull-down to GND is available on each input, so
that if the pin is left floating, it can be driven to a known
state.
A glitch filter (the same as that provided for the analog
inputs) is available to provide noise immunity/ signal de-
bouncing.
If selected to edge detect, then the digital block can be
programmed to output a pulse of width programmable

input pins. Once selected as a secondary detector, the analog
circuit is programmed exactly the same way as the primary
circuit. This is shown in the window below.

From the inputs window it is also possible to navigate to the
sequencing engine, outputs or warnings page by simply left
clicking in one of the boxes indicated in figure 43.
