DS630F1 23
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).
