Introduction

EPWM HR UpDown

This example modifies the MEP control registers to show edge displacement for high-resolution period with ePWM in Up-Down count mode due to the HRPWM control extension of the respective ePWM module.

External Connections

• Pin can be connected to high resolution oscilloscope (1 GHz) to observe the edge displacement.

AM263X-CC

When using AM263x-CC with TMDSHSECDOCK (HSEC180 controlCARD Baseboard Docking Station)

• Capture waveform on HSEC Pin 49, 51 for epwm0
• Capture waveform on HSEC Pin 53, 55 for epwm1
• Capture waveform on HSEC Pin 50, 52 for epwm2
• Capture waveform on HSEC Pin 54, 56 for epwm3
• Capture waveform on HSEC Pin 57, 59 for epwm4
