The logical 1 indicates the device is busy because of a Serial Bus transaction or another LPC bus
transaction. With checking this bit, multiple LPC drivers can use W83627HF hardware monitor without
interfering with each other or a Serial Bus driver.
It is the user's responsibility not to have a Serial Bus and LPC bus operations at the same time.
This bit is：
Set： with a write to Port x5h or when a Serial Bus transaction is in progress.
Reset： with a write or read from Port x6h if it is set by a write to Port x5h, or when the Serial Bus
transaction is finished.
