Functional Description
The following figure shows motor jittering produced by the phase B and A pulses
respectively. The first highlighted transition causes a jitter on the FTM counter value near
the maximum count value (MOD). The second indicated transition occurs on phase A and
causes the FTM counter transition between the maximum and minimum count values
which are defined by MOD and CNTIN registers.
The appropriate settings of the phase A and phase B input filters are important to avoid
glitches that may cause oscillation on the FTM counter value. The preceding figures
show examples of oscillations that can be caused by poor input filter setup. Thus, it is
important to guarantee a minimum pulse width to avoid these oscillations.
36.4.26 BDM Mode
When the chip is in BDM mode, the BDMODE[1:0] bits select the behavior of the FTM
counter, the CH(n)F bit, the channels output, and the writes to the MOD, CNTIN, and
C(n)V registers according to the following table.
