25 CWG - Complementary Waveform Generator

The Complementary Waveform Generator (CWG) produces half-bridge, full-bridge, and steering of PWM waveforms. It is backwards compatible with previous CCP functions. The PIC16(L)F18455/56 family has 3 instance(s) of the CWG module.

The CWG has the following features:

• Six Operating Modes:
  • Synchronous Steering mode
  • Asynchronous Steering mode
  • Full-Bridge mode, Forward
  • Full-Bridge mode, Reverse
  • Half-Bridge mode
  • Push-Pull mode
• Output Polarity Control
• Output Steering
• Independent 6-Bit Rising and Falling Event Dead-Band Timers:
  • Clocked dead band
  • Independent rising and falling dead-band enables
• Auto-Shutdown Control with:
  • Selectable shutdown sources
  • Auto-restart option
  • Auto-shutdown pin override control
