* Detailed Description:
*
* eMIOS0 ch0 is set to SAIC mode generating interrupt on falling edge.
* The IGF ch16, connected to eMIOSch0, is set to filter low pulses <1.5us
* Intergation filter type is used for falling edge with given threshold.
* eMIOS interrupt is called if input signal low pulse is longer than 1.5us.
*
