These pins are sampled when power is applied or by
issuing a PMBus Restore command (See Application
Note AN13).

Pin-strap Settings: This is the simplest implementa-
tion method, as no external components are required.
Using this method, each pin can take on one of three
possible states: GND, OPEN, or HIGH. These pins
can be connected to the VR or V25 pins for logic
HIGH settings, as either pin provides a regulated volt-
age greater than 2V. Using a single pin, the user can
select one of three settings, and using two pins, the
user can select one of nine settings.
Resistor Settings: This method allows a greater range
of adjustability when connecting a finite valued resis-
tor (in a specified range) between the multi-mode pin
and SGND. Standard 1% resistor values are used, and
only every fourth E96 resistor value is used so that the
device can reliably recognize the value of resistance
connected to the pin while eliminating the errors asso-
ciated with the resistor accuracy. A total of 25 unique
selections are available using a single resistor.
I
can be configured via the I
standard PMBus commands. Additionally, any value
that has been configured using the pin-strap or resistor
setting methods can also be re-configured and/or veri-
fied via the I
for details.
