2. This filter is implemented to wait for comparator stabilization and avoid any wrong information during start-up.
3. This delay represents the number of clock cycles needed to generate an event as soon as the comparator output or MCO

Example: In tachogenerator mode, this means that capture is performed on the 4th clock cycle after comparator
