6.2.2.6 PWM Characteristics
Characteristics of the PWMs are as follows:
- 16-bit registers
- Wide range of programmable deadband for the PWM output pairs
- Change of the PWM carrier frequency for PWM frequency wobbling as needed
- Change of the PWM pulse widths within and after each PWM period as needed
- External-maskable power and drive-protection interrupts
- Pulse-pattern-generator circuit, for programmable generation of asymmetric, symmetric, and four-space vector PWM waveforms
- Minimized CPU overhead using auto-reload of the compare and period registers
- The PWM pins are driven to a high-impedance state when the PDPINTx pin is driven low and afterPDPINTx signal qualification. The PDPINTx pin (after qualification) is reflected in bit 8 of the COMCONx register.
- PDPINTA pin status is reflected in bit 8 of COMCONA register.
- PDPINTB pin status is reflected in bit 8 of COMCONB register.
- EXTCON register bits provide options to individually trip control for each PWM pair of signals
