The SIES Register is used to indicate the present signal state which the USB SIE received and also determines
whether the USB SIE has to change the device address automatically.
The MISC register is actually a command + status to control the desired FIFO action and to show the status of the de-
sired FIFO. Every bit s meaning and usage are listed as follows:

This bit is used to configure the USB SIE to automatically change the device address with
the value of the Address+Remote_WakeUp Register (42H).
When this bit is set to 1 by F/W, the USB SIE will update the device address with the value
of the Address+Remote_WakeUp Register (42H) after the PC Host has successfully read
the data from the device by the IN operation. The USB SIE will clear the bit after updating
the device address.
Otherwise, when this bit is cleared to 0, the USB SIE will update the device address imme-
diately after an address is written to the Address+Remote_WakeUp Register (42H).
This bit is used to indicate when there are some errors that occurred when the FIFO0 is ac-
cessed.
This bit is set by the USB SIE and cleared by F/W.
Unused bit, read as 0
This bit is for masking the NAK interrupt when MNI= 1 , the default value= 0
