A write to OEMCFG0 will result in any A/D conversion in progress being aborted and the result discarded. The A/D will begin a
new conversion sequence once the write operation is complete.
All bits in OEMCFG0 are non-volatile except DFLT and RST. A valid OEM password is required for access to this register.

Operation
0 = no action; 1 = reset
Issuing a software reset by setting RST high is equivalent to
a full power cycle of the MIC3003.
If OEMCFG3 bit 7 (QGPOM) is low, this bit determines
whether the QGPO output is high (undriven) or low (driven-
open-drain).
If QGPOM is high (Reset mode), this bit has no function
1 = diode fault; 0 = OK.
1 = enabled; 0 = hi-Z
