Micro Edge Positioning (MEP) step size

Maximum MEP step size is based on worst-case process, maximum temperature and maximum voltage. MEP step size will increase
with low voltage and high temperature and decrease with voltage and cold temperature.
Applications that use the HRPWM feature should use MEP Scale Factor Optimizer (SFO) estimation software functions. See the TI
software libraries for details of using SFO function in end applications. SFO functions help to estimate the number of MEP steps per
SYSCLKOUT period dynamically while the HRPWM is in operation.
