Example:
The code for 1.8 V in a 1.8 V channel is:
1.8
0.0094
Similarly, the voltage, given the code in a particular
channel, is calculated as follows:
Voltage + Code 1 LSB
where:
10 V is connected to the 12 V channel.
1 LSB = 0.0625.
Code = 160 decimal.

Voltage Measurement and Limit Registers
The corresponding register locations for voltage
measurements are listed in Table 17. Each voltage
measurement channel has a high and low voltage limit
associated with it. The voltage measurements are compared

with these limits. The results of these comparisons are stored
in status registers. A Logic 0 indicates an in-limit condition,
and a Logic 1 indicates an out-of-limit condition. The
ADT7462 can generate an ALERT, if configured to do so,
when a status bit is set. For more information on the status
