MDIO
MDIO is a control inteface between CPU (IC100) and L2SW LSI (IC502). When system starts up, CPU controls L2SW LSI via
MDIO.
MDIO has two signals, MDC is clock, and MDIO is I/O signal. And take care that MDIO has multiplex bus cycle, write and read cycle
changes during a transaction.

I2C
USB HUB LSI (IC603) is controlled by CPU (IC100) via I2C interface.
When CPU starts up, USB HUB is initialized.
When CPU starts up, USB HUB is initialized.

SIO
This is typical wave form of RS232C Serial I/O.
RS232C Tx Data signal is described as below.
When you measure the wave form, please make sure, SIO cable should be connected between KX-NS1000 and external PC.
When cable is disconnected, Tx Data signal will stop automatically.
