Q&A: How to work around the incorrect CLKOUT settings in am_hal_clkgen_clkout_e?

 Full question(s):

The values in the enumeration am_hal_clkgen_clkout_e in SDK2.1.0 do not match Apollo3's datasheet 0.9.1. Thus the CLKOUT does not function as expected.  How can this be worked around?

Answer(s):

Setting "AM_HAL_CLKGEN_CLKOUT_LFRC_512 = 0x23" and "AM_HAL_CLKGEN_CLKOUT_LFRC_0_0004 = 0x31" in the enumeration will correct all settings.  These fixes will be in the next SDK release.

This fix and other intended fixes are listed in the KB article AmbiqSuite SDK - Known Defects and Fixes.
