ACTION
The AIN1 register is around 0.
The result is dependent on the circuit setup of AUXIN1. If REF is driven to VAA, all the
cell input measurements are lower by 1V. If REF is pulled low to AGND, cells 1 to 10
measurement results are all full scale (5V). The DIAG register changes to 0x296 from 0x5D4.
Cells 1 to 12 measurement results vary from 3V to 5V. The DIAG register varies from 0x300
to 0x800. ALRTREF of the FMEA register is set to 1, ALRTFMEA of the STATUS register is
set to 1.
Cell 1 to 12 measurement results are all full scale (5V).
The DIAG register changes to 0x296 from 0x5D4.
No effect.
I
ALRTVDDL of the FMEA register is set to 1. ALRTFMEA of the STATUS register is set to 1.
