Enhanced High-Resolution Pulse-Width Modulator (eHRPWM)
14.1.3 Register Mapping
Table 14-1 shows the complete ePWM module control and status register set grouped by submodule.
Each register set is duplicated for each instance of the ePWM module. The start address for each ePWM
register file instance on a device is specified in the appropriate data manual.
(1)
Locations not shown are reserved.
(2)
These registers are only available on ePWM instances that include the high-resolution PWM (HRPWM) extension; otherwise,
these locations are reserved. See your device-specific data manual to determine which instances include the HRPWM.
