Figure 152. Example 2: waveforms for zero-crossing detection with sampling at fSCF

This filter is implemented to wait for comparator stabilization and avoid any wrong information during start-up.

This delay represents the number of clock cycles needed to generate an event as soon as the comparator output or MCO

outputs change.

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

commutation, that is, there is a variation of (1/fmtc) or (1/fSCF) depending on the case.
