This module combines multiple delay lines in a single module and a simplified calibration system by using a dedicated calibration delay line. For each ePWM module there is one HR delay line.
The HRPWM module offers PWM resolution (time granularity) that is significantly better than what can be achieved using conventionally derived digital PWM methods. The key points for the HRPWM module are:
The minimum SYSCLKOUT frequency allowed for HRPWM is 60 MHz.
When dual-edge high-resolution is enabled (high-resolution period mode), the PWMxB output is not available for use.
For more information on the HRPWM, see the High-Resolution Pulse Width Modulator (HRPWM) chapter in the TMS320F2803x Technical Reference Manual.
