TMS320F28388D: Are all ePWM(s) created equal?

Part Number: TMS320F28388D

Do all the ePWM have same feature and characteristics? On the Submodule Overview {Section 26.1.1-Enhanced Pulse Width Modulation (ePWM) of the TMS320F2838x Real-Time Microcontrollers With Connectivity Manager documents },

The second, third, and forth sentences say "Multiple ePWM modules are instanced within a device as shown in Figure 26-1. Each ePWM instance is identical with one exception. Some instances include a hardware extension that allows more precise control of the PWM outputs. This extension is the high-resolution pulse width modulator (HRPWM) and is described in Section 26.15."

What is the "one exception", I cannot find anywhere in section 26 nor Figure 26-1 should any different between each ePWM?
