ViPInt16 first_latched_reg
-This parameter returns the first input channel which crosses the programmed threshold voltage.
ViPInt16 raw_data
-This returns the 16 bit value that represents the current unconditioned [raw] state of the inputs.
ViPInt16 conditioned_data
-This returns the 16 bit value that represents the current conditioned state of the inputs.
Return Values: | Returns VI_SUCCESS if successful, else returns error | |
| value. |

Description | This is an application function that shows how | the |
| user can use core functions to enable/disable the | |
| specified channels for interrupt generation and | |
| configure the specified channels’ various parameters | |
| such as offset, polarity and | It |
| returns the value of the First Latched register which | |
| records the first input channel to cross its threshold | |
| and queries the current state of the inputs. | Note |
that this function resets the module to its default state.
