small to fit in the AIN Output Register.

CRDY

Conversion Ready. Indicates a new conversion is ready.

OD1, OD2

Modulator oscillation detect. Set when the modulator oscillates due to an input above Full

Scale. Note that the level at which the modulator oscillates is significantly higher than the Input

Voltage Range.

FOR1, FOR2

FILT out of range. Set when the calibrated voltage value is too large for the FILT register.

IC

Invalid Command. Normally logic 1. Set to logic 0 if the host interface is strobed with an 8-bit

word that is not recognized as one of the valid commands (see Section 4.1, Commands).
