ADT7462
Function Description: Easy Configuration
Options
There are a number of multifunctional pins on the
ADT7462 that need to be configured on powerup to suit the
desired application. Note that due to the large number of pins
that need to be configured, it could take several SMBus
transactions to achieve the required configuration. For this
reason, the ADT7462 has five easy configuration options.
The user sets a bit in the easy configuration option register
(0x14) to set up the required configuration (see Table 5).

Once the most convenient easy configuration option has
been set, the user can configure any of the pins individually.
The setup complete bit (Bit 5 of Register 0x01) must then be
set to 1 to indicate that the ADT7462 is configured correctly,
and then monitoring of the selected channels begins.
The following is a detailed description of the five easy
configuration options that are available.
Configuration Option 1
Configuration Option 1 is the default configuration. It is
also the most suitable for thermal monitoring, voltage
monitoring, and fan control for single and dual processor
