Using the noted EVM. Not sure I understand the operation of the VSYSMIN register. My understanding is - VSYS voltage will be equal to the greater of VSYSMIN voltage, or VBAT. Writing to VSYSMIN didn't have the effect I expected.
Read VSYSMIN - 0x1A (26). I decode this a 9V. Battery is a 3S, and nominal voltage is about 10.910 to 11.550. PROG jumper is set to 3S.
Wrote -x26 (38) to VSYSMIN (and read it back). 38 should be 12V. I expected VSYS to jump to 12V. But, it didn't change.
What don't I understand? Or what other register do I need to write?
