Updated June 2007
============
There are now two versions of the SFO library - SFO_TI_Build.lib and SFO_TI_Build_V5.lib (V2-V4 were INTERNAL TI releases):

SFO_TI_Build.lib - original SFO library which supports up to 4 HRPWM channels (ePWM 1-4)
SFO_TI_Build_V5.lib - SFO library which supports up to 16 HRPWM channels (ePWM 1-16)  with some optimizations

For a description of the two SFO library versions including differences, functionality, and constraints 
during usage, consult the HRPWM Reference Guide (literature number: spru924)
