4.1 Strap in Mode
Strap in configuration mode is the quickest and easiest way to get started. In this mode, the
KSZ8895ML acts as a standalone 5 port switch. The user has to simply set the board’s
configuration jumpers to the desired settings and apply power to the board. The user can also
change jumper settings while power is applied to the board and press the convenient manual reset
button for the new settings to take effect. Note that even if there is no external strap in values are set,
internal pull up and pull down resistors will set the KSZ8895ML default configuration. Section
4.1.1 covers each jumper on the board and describes its function.
To start in strap in configuration mode, make sure that JP1 and JP2 are open and JP3 and JP9 are
closed. In this mode, pins (PS1,PS0)=(0,0), the chip will start automatically, after trying to read the
external EEPROM, if EEPROM does not exist, the chip will use the default values and the strap
option setting for all internal registers.
