Figure 329. Example of counter operation in encoder interface mode.
Figure 330 gives an example of counter behavior when tim_ti1fp1 polarity is inverted (same
configuration as above except CC1P=’1’).
Figure 330. Example of encoder interface mode with tim_ti1fp1 polarity inverted.
The Figure 331 below shows the timer counter value during a speed reversal, for various
counting modes.
