8-bit Peripheral Highlights
Various clock sources: external, system clock,
independent 64 MHz
Various input sources: comparators, external
pins
Blanking control for transient filtering
Single 16-bit PWM
– with up to 6 steerable outputs
Complementary 16-bit PWM
– with up to 3 steerable output pairs
Independent rising/falling edge control
Dead band with independent rise and fall control
Polarity control/auto shutdown and restart
Flexible PWM output modes:
– Push/pull, pulse skipping, 3-phase, fixed duty
cycle, brushed DC with forward/reverse
Output gating – externally controlled activate/
deactivate
Increased frequency control with dead-band control for the synchronous switches
Provides auto shut down, polarity control and increased duty cycle performance
