Software Feature Description
Output Level
(pulldown window): Select High or Low to set the level of the GPIO2 output pin (only
available if GPIO2 is set as an output).
GPIO2 Interrupt Source
(box): Check box if you want a GPIO2 input signal to toggle the INT pin and
turn on the Acknowledge LED (stays on momentarily until it is read). Only available if GPIO2 is set as
an input.
Interrupt Edge
(pulldown window): Choose Rising or Falling Edge for triggering GPIO2 input interrupt
(only available if GPIO2 is set as an input).
GPIO3
Function
(pulldown window): Defines if the GPIO3 is an input or output.
If set as an input, the GPIO3 input signal triggers the data conversion routine (see SM1/SM2/SM3 tab).
If set as an output, the
Output Level
pulldown window appears and GPIO3 is set according to the
Output Level
pulldown window.
Output Level
(pulldown window): Select High or Low to set the level of the GPIO3 output pin (Only
available if GPIO3 is set as an output).
Mask INT Interrupts
Sixteen signals are monitored by the ADC for fault conditions, and on detection of a fault, the ADC
toggles the INT pin. If the box of a particular signal is checked (masked), the reporting of that fault via
the INT pin is disabled.
Sleep Mode Settings
The ADC can be put in sleep mode by a fault (voltage out of range) of any one of the eight power
output signals. Check the box(s) for the signal(s) that should put the ADC in sleep mode when in fault
status.
