Appendix A

Appendix A SFO Library Software - SFO_TI_Build_V5.lib

This appendix includes a detailed description of the software routines in SFO_TI_Build_V5.lib which

supports up to 16 HRPWM channels.

A.1 SFO Library Version Comparison

Table 12 includes a high-level comparison between SFO_TI_Build.lib and SFO_TI_V5.lib. A detailed

description of SFO_TI_Build_V5.lib follows the table, and more information on SFO_TI_Build.lib can be

found in Section 2.4.

In SFO_TI_Build_V5.lib/SFO_TI_Build_V5B.lib, the diagnostic software has been optimized to use less

memory, to minimize the calibration time, and to support up to 16 HRPWM channels. Table 13 provides

functional description of the two SFO library routines in SFO_TI_Build_V5.lib/SFO_TI_Build_V5B.lib.
