8-bit Peripheral Highlights
Complementary Waveform Generator (CWG)/Complementary Output Generator (COG)
Provides non-overlapping complementary waveform
Various input sources inclusive of:
– Comparators, PWM, CLC, NCO
Blanking control for transient filtering
(available with COG only in PIC12F752)
Phase control for output delay
(available with COG only in PIC12F752)
Independent rise and fall
Dead band control
Auto shutdown/restart
Polarity control
Works with multiple peripherals
Fewer components and less space
Lower power
Improved switching efficiencies
CWG or COG frequency is determined
by frequency of PWM
CWG or COG provide dead-band
control for the synchronous switches
Use CWG’s or COG’s advanced
features to provide auto shut down,
polarity control
