Notes on using Interrupt bits
If the Auto Start bit (AS) is set this will start the interrupt on power up and
set the Timed Interrupt Enabled bit (TIE) automatically, allowing the
interrupt to execute. Shown in the example above.
If the AS bit is not set then the TIE bit must be set through the ladder logic
in order for the interrupt to execute.
The User Interrupt Enable bit (UIE) determines if the interrupt executes or
not.
