A write to OEMCFG1 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 OEMCFG1 are non-volatile and will be maintained
through power and reset cycles. A valid OEM password is required for access to this register.

Function
Operation
D[7]
INV
Inverts the APC op-amp inputs.
When set to “0” the BIAS DAC
output is connected to the “+”input
0 = emitter follower (no inversion);
1 = common emitter (inverted); read/write; non-volatile.
and FB is connected to the “–” input
of the op amp. Set to “0” to use the
ADC feedback loop.
D[6]
GAIN
Sets the feedback voltage range by
changing the APCDAC output
swing; 0-V REF for optical feedback,
1 = V REF /4 full scale;
0 = V REF full scale; read/write; non-volatile.
0-V REF /4 for electrical feedback.
D[5]
BIASREF
Selects whether FB and VMPD are
1 = V DD ; 0 = GND; read/write; non-volatile.
referenced to ground or V DD and
selects feedback resistor termination
voltage (V DDA or GNDA).
D[4:2]
RFB[2:0]
Selects internal feedback resistance.
(Resistors will be terminated to V DDA
or GNDA according to BIASREF.)

SPOL
V BIAS source vs. sink drive.
Polarity of shutdown output, SHDN,
when active.
1 = source (NPN),
