Table 5.16 List of Digital Input Parameters
5.10.1.1 Digital Input Function Assignment
Setting the digital input configuration entry for the digital input, to the appropriate handler function number,
configures the functionality of each input. The table below lists the functions that can be assigned. Only the NULL
function can be assigned to more than one digital input. If an attempt is made to map a function twice a mapping
error is indicated.
For Edge Triggering:
The handler function is not called repetitively, but rather the handler function is called when: -
• Initially setting up the digital input, when no previous function assigned to the input (i.e first time).
• A transition occurs in the digital input.
• Change the setting of the digital input invert.
