ADM1064
VXn PINS AS DIGITAL INPUTS
As mentioned previously, the VXn input pins on the ADM1064
have dual functionality. The second function is as a digital input
to the device. Therefore, the ADM1064 can be configured for up
to five digital inputs. These inputs are TTL/CMOS-compatible.
Standard logic signals can be applied to the pins: RESET from
reset generators, PWRGOOD signals, fault flags, manual resets,
and so on. These signals are available as inputs to the SE, and
can be used to control the status of the PDOs. The inputs can be
configured to detect either a change in level or an edge.

When configured for level detection, the output of the digital
block is a buffered version of the input. When configured for
edge detection, once the logic transition is detected, a pulse of
programmable width is output from the digital block. The width
is programmable from 0 μs to 100 μs.
The digital blocks feature the same glitch filter function that is
available on the SFDs. This enables the user to ignore spurious
transitions on the inputs. For example, the filter can be used to
debounce a manual reset switch.
When configured as digital inputs, each of the VXn pins has a
weak (10 μA) pull-down current source available for placing the
input in a known condition, even if left floating. The current
source, if selected, weakly pulls the input to GND.
