Alternative boot mode switch (S300-A)
Switch S300-A is used to activate the alternative boot mode of the netX 90.
In alternative boot mode, a maintenance firmware will be started, which
might be useful for firmware update or dealing with multiple firmware
versions. Switch S300-A is evaluated after a reset of the chip during start-
up phase. When S300-A is switched on, the RUN# signal (pin #39) of the
netX 90 is connected to GND via a 1kΩ resistor, see figure below:

7.2.1.2
Console mode switch (S300-B)
You can activate the console mode of the netX 90 using switch S300-B.
This signal is evaluated after a reset of the chip during start-up phase.
When S300-B is switched on, the RDY# signal (pin #38) of the netX 90 is
connected to GND via a 1kΩ resistor, see figure below:
