• IGFON: Input Glitch Filter Status
0: Input Glitch Filter is off.
1: Input Glitch Filter is on.
Only present when IGF is used. Refer to the Module Configuration section at the end of this chapter.
To enable Input Glitch Filtering, EN bit must be set to 1, as well as one of IGFF or IGFR.
This bit is Read-only, and can be used to detect that configuration is effective. It incurs some delay compared to the writing of
IGFF, IGFR, or EN.
• IGFF: Input Glitch Filter Fall
0: No event detection on falling edge.
1: Event detection through Input Glitch Fiilter on falling edge.
Only present when IGF is used. Refer to the Module Configuration section at the end of this chapter.
To enable Input Glitch Filtering, EN bit must also be set to 1.
Both IGFF and IGFR can be combined.
• IGFR: Input Glitch Filter Rise
0: No event detection on rising edge.
1: Event detection through Input Glitch Fiilter on rising edge.
Only present when IGF is used. Refer to the Module Configuration section at the end of this chapter.
To enable Input Glitch Filtering, EN bit must also be set to 1.
Both IGFF and IGFR can be combined.
• EN: Event Shaper Enable
0: Event Shaper is off.
1: Event Shaper is on.
To enable Input Glitch Filtering, IGFR and/or IGFF must also be set to 1.
