PWM Blocks - Block Reference
Comprehensive PWM (Pulse Width Modulation) blocks for motor control, power conversion, and signal generation across all MCHP Blockset supported families.
Device Family Support:
- dsPIC30F/33F/33E: → MCHP_PWM
- dsPIC33C/CH/CK: → MCHP_PWM_HighSpeed

dsPIC Family PWM Blocks
- MCHP_PWM - Standard PWM for dsPIC30F/33F/33E with dead-time and fault protection
- MCHP_PWM_HighSpeed - High-Speed PWM with independent time bases and 4 output modes (dsPIC33C/CH/CK)
- MCHP_PWM_HighSpeed_Override - PWM Override Control for emergency shutdown and diagnostics
- MCHP_PWM_HS_FEP - High-Speed PWM with Fine Edge Positioning, 16× resolution High-Resolution mode (dsPIC33A)
Motor Control PWM
- MCHP_MCPWM - Motor Control PWM with advanced fault handling, dead-time compensation, and leading-edge blanking (PIC32MK, dsPIC33C, dsPIC33A)
SAM/ARM Family PWM Blocks
- MCHP_PWM_SAM7x - SAM7x PWM peripheral for SAME5x/SAME7x/SAMC2x/SAMD2x families
- MCHP_PWM_SAM7x_Override - SAM7x Override control for PWM outputs
