Least Significant Byte of the Vendor ID.
Reserved. {Note: Software must never write a ‘1’ to these bits}
Reset the SMBus Interface and internal memory back to RESET_N assertion
default settings. {Note: During this reset, this bit is automatically cleared to
its default value of 0.}
0 = Normal Run/Idle State.
1 = Force a reset.
Write Protect: The external SMBus host sets this bit after the Hub’s internal
memory is loaded with configuration data. {Note: The External SMBus Host
is responsible for verification of downloaded data.}
0 = The internal memory (address range 01-10h) is not write protected.
1 = The internal memory (address range 01-10h) is “write-protected” to
prevent unintentional data corruption.}
{Note: This bit is write once and is only cleared by assertion of the external
RESET_N pin.}
USB Attach & power-down the SMBus Interface.
0 = Default; SMBus slave interface is active.
1 = Hub will signal a USB attach event to an upstream device, Note: SMBus
Slave interface will completely power down after the ACK has completed.
{Note: This bit is write once and is only cleared by assertion of the external
RESET_N pin.}
