Figure 14-27. PSCR behavior versus PSCr Input A in Mode 9
The output frequency is not modified by the occurrence of significative edge of retriggering input.
Only the output is deactivated when significative edge on retriggering input occurs.
Note: In this mode the output of the PSCR becomes active during the next ramp even if the Retrig-
ger/Fault input is active. Only the significative edge of Retrigger/Fault input is taken into account.
Figure 14-28. PSCR behavior versus PSCr Input B in Mode 9
The retrigger event is taken into account only if it occurs during the corresponding On-Time.
