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.
Bit(s)
Function
Operation
D[7]
RST
0 = no action; 1 = reset
Issuing a software reset by setting RST high is equivalent to
a full power cycle of the MIC3003.
D[6]
QGPOS
Determines the state of QGPO in
GPO mode
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
D[5]
DFLT
Diode fault flag.
1 = diode fault; 0 = OK.
D[4]
OE
Output enable for SHDN, VMOD,
and VBIAS.
1 = enabled; 0 = hi-Z
D[3]
MODREF
Selects whether VMOD is
referenced to ground or VDD.
1 = VDD; 0 = GND
D[2:0]
VAUX[2:0]
Selects the voltage reported in
VINh:VINl.
000 = VIN
001 = VDDA
010 = VBIAS
011 = VMOD
100 = APCDAC
101 = MODDAC
110 = FLTDAC
