Figure 13-29. PSCR behavior versus PSCr Input A in Mode 14
The output frequency is not modified by the occurrence of significative edge of retriggering input.
Figure 13-30. PSCR behavior versus PSCr Input B in Mode 14
The output is deactivated while retriggering input is active.
The output of the PSCR is set to an inactive state and the corresponding ramp is not aborted. The output
stays in an inactive state while the Retrigger/Fault input is active. The PSCR runs at constant frequency.
