This bit indicates ”1” when the nodeNumber filed has valid
data.
0b
This bit indicates ”1” when the MB86613S is the root
device.
0b
This bit indicates the cable power status.
3FFh
These bits store the bus number inserted in the packet
header.
undefined These bits indicate the device’s node number.
3.2.24. PHY Control
PHY control register is used to allow software to access the PHY registers. When reading out the data from
the PHY registers, set the required register address in the regAddr and set the rdReg. rdDone is
cleared at this time. After that, the rdDone and IntEvent.PhyRegRecv bits are set if the data in the specified
address is stored in the rdData and the PHY register address is stored in the rdAddr. the rdReg is cleared at
this time. When writing the data to the PHY registers, set the required register address in the regAddr and
write the data in the wrData, and set the wrReg. the rdDone is cleared at this time. the rdDone is then set if the
required data is written to the wrData. The wrReg is cleared at this time.
Please do not set the rdReg and wrReg bits while the rdDone is cleared.

This bit indicates ”0” when rdReg or wrReg is set. After
that, the bit indicates ”1” when the r/w operation to
PHY registers is done.
undefined These bits indicate the PHY register address in which the
data is specified in rdData bits
undefined These bits indicate the data in the PHY register specified
in the rdAddr bits.
0b
This bit is used for reading out the data from the register
address specified in the regAddr bits.
0b
This bit is used for writing the data stored in the wrData bits
to the register address specified in the regAddr bits.
undefined Specify the PHY register address.
undefined Specify the data written to the PHY register.
