MAX11068 Evaluation System
Table_8._Threshold_Registers
*The maximum voltage setting is 5.0000V.
Table_9._AIN1_and_AIN2_Controls
*These bits work in parallel with the ALRMUTEN and ALRMOTEN registers.
For all the threshold registers, the data (D[11:0]) is con-
tained in the upper 12 bits of the 16-bit register. When
entering data into the Under-Temperature_ Threshold_
(AINUT) and Over-Temperature_ Threshold (AINOT)
edit boxes, enter only the hex value of the upper 12 bits.
The lower nibble of all threshold registers are ignored
during a write and are read back as zeros.
The Voltage_Measurements tab (Figure 7) displays the
results for the ADC conversions on cells 1–12, as well
as the results for TOTAL, MAXCELL, and MINCELL. The
register contents are displayed in the grid as voltages.
The checkboxes at the top of the tab and their associ-
ated Configure_ Cells_ (F9) button are used to enable
a cell for measurement. These checkboxes have the
same function as the CELL_EN checkboxes on the
Configuration tab. See the ADC Scan section for details
on setting up and initiating an ADC scan.

The auxiliary analog inputs (AIN1 and AIN2), diagnostic
(DIAG), and failure mode effects analysis (FMEA) reg-
isters are accessed from this tab (Figure 8). The tab is
divided into four group boxes: AIN1,_ AIN2, DIAG,_ and_
Failure_ Mode_ Effects_ Analysis_ (FMEA). The DIAG
group box displays the 12-bit result of the self-diagnostic
measurement and the FMEA group box displays the
FMEA alerts and provides access to their associated
mask bits. The AIN_ group boxes provide the controls
listed in Table 9.
The AIN1, AIN2, and DIAG conversions must first be
enabled before a valid conversion value can be read
from the AIN or DIAG registers. A scan of the AIN_
channel is enabled by selecting the AIN_EN checkbox
located on the Enables tab (Figure 10). A self-diagnos-
tics conversion is enabled by selecting the DIAGEN_
checkbox located on the Enables tab. See the Enables
Tab and ADC Scan sections.
