4.9.1 CWG
Complementary Waveform Generator
4.9.1.1 Introduction
The Complementary Waveform Generator (CWG) produces a complementary waveform with dead-band delay from a selection of input sources. The CWG comes with features like selectable clock sources, input sources, output enable control, and selectable dead-band customization. Its auto-shutdown feature and pin override control enhance system efficiency and flexibility.

Functions
void CWG_Initialize (void)
Initializes the CWG module. This is called only once before calling other CWG APIs.
void CWG_LoadRiseDeadbandCount (uint8_t dutyValue)
Sets the duration of the dead-band interval on the rising edge of the input source signal.
void CWG_LoadFallDeadbandCount (uint8_t dutyValue)
Sets the duration of the dead-band interval on the falling edge of the input source signal.
void CWG_AutoShutdownEventSet (void)
Puts the CWG outputs into the Auto-Shutdown state.
void CWG_AutoShutdownEventClear (void)
Resumes the operation of the CWG when the Auto-Shutdown state is disabled.
