The MEP logic is capable of placing an edge in one of 255 (8 bits) discrete time steps (see the device data sheet for typical MEP step size). The MEP works with the TBM and CCM registers to be certain that time steps are applied and that edge placement accuracy is maintained over a wide range of PWM frequencies, system clock frequencies, and other operating conditions. Table 22-19 shows the typical range of operating frequencies supported by the HRPWM.
