Information

FTM counter
channel (n) output
(before fault control)
FAULTIN bit
channel (n) output
(after fault control with
manual fault clearing
and POLn=0)
the beginning of new PWM cycles
FAULTF bit
FAULTF bit is cleared
The channel (n) output is after the fault control with manual fault clearing and POLn = 0.

Figure 37-236. Fault Control with Manual Fault Clearing
37.4.16.3 Fault Inputs Polarity Control
The FLTjPOL bit selects the fault input j polarity (where j = 0, 1, 2, 3).
• If FLTjPOL = 0, the fault j input polarity is high, so the logical one at the fault input j
indicates a fault.
• If FLTjPOL = 1, the fault j input polarity is low, so the logical zero at the fault input j
indicates a fault.
37.4.17 Polarity Control
The POLn bit selects the channel (n) output polarity.
• If POLn = 0, the channel (n) output polarity is high, so the logical one is the active
state and the logical zero is the inactive state.
• If POLn = 1, the channel (n) output polarity is low, so the logical zero is the active
state and the logical one is the inactive state.
