How to get the LAN9303 into I2C managed mode
In order to set the LAN9303 into I2C managed mode where you can configure the chip using I2C, strap MNGT1
to 1
and strap MNGT0
to 0
. Since the MNGT[1:0]
strap pins have an internal pull-up, you only need to strap MNGT0
(pin 26
on the QFN package) to GND using a 10kΩ
resistor from this pin to GND
.
