3.1 Configuration Options
3.1.1 Strap-in Configuration
Strap-in configuration is used to set the basic modes of operation so that KSZ8463 powers up in the right
modes. This is accomplished by setting available configuration jumpers which are used at device power-
up. Simply set the board’s configuration jumpers to the desired settings and apply power to the board. The
configuration can be changed while power is applied to the board by changing the jumper settings and
pressing the manual reset button for the new settings to take effect. Note that even if no external strap-in
jumpers are set, internal pull-up and pull-down resistors will set the KSZ8463ML/RL to the default
configuration. The following table covers each jumper used for the strap-in option and describes its
function.
