Figure 14-87. PWMEN and PWM Outputs in Independent Operation
Figure 14-88. PWMEN and PWM Outputs in Complementary Operation
When the PWMEN bit is cleared:
•
The PWM
n
outputs lose priority on associated outputs unless OUTCTL
n
= 1
•
The PWM counter is cleared and does not count
•
The PWM generator forces its outputs to zero
•
The PWMRF flag and pending CPU interrupt requests are not cleared
•
All fault circuitry remains active unless FEN
m
= 0
•
Software output control remains active
•
Deadtime insertion continues during software output control
14.8.1.1
Register Write Protection
The following configuration registers and bits can be write protected:
PMFCFG0, PMFCFG1, PMFCFG3, PMFFEN, PMFQSMP0-1, PMFENCA[RSTRTA,GLDOKA],
PMFENCB[RSTRTB,GLDOKB], PMFENCC[RSTRTC,GLDOKC], PMFDTMA,B,C, PMFDMP0-5,
PMFOUTF
NOTE
Make sure to set the write protection bit WP in PMFCFG0 after configuring
and prior to enabling PWM outputs and fault inputs.
14.8.2
BLDC 6-Step Commutation
14.8.2.1
Unipolar Switching Mode
Unipolar switching mode uses registers PMFOUTC and PMFOUTB to perform commutation.
