These filters do not reject 50/60 Hz. Repeatability for these filters is strongly dependent
on how much 50/60Hz noise is in the system.

Description Notes
0-1
These 2 bits define module
operation mode,
0: Idle: Module is ready to RUN,
and I/O is off.
1: RUN: Module is under RUN,
and I/O is on.
2: Error: Error happens, and I/O is
off.
3: Busy: Module is busy, cannot go
to RUN, and I/O is off.
2
This bit defines module user
interrupt mode,
0: User Interrupt is disabled.
1: User Interrupt is enabled. The IF4U does not support this
functionality; this bit is always off (0).
3 Reserved
4 SW Error
Trigger condition – Watchdog timer
triggered.
5 ADC Error
Trigger condition – ADC
communication stops or ADC has not
sampled data for long period of time.
6 Calibration Error
Trigger condition – blank calibration or
calibration checksum error.
7 Configuration Error
Wrong bits set in channel
configuration.
