The SIES Register is used to indicate the present signal state which the SIE receives and also defines whether the SIE
has to change the device address automatically.

This bit is used to configure the 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 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 SIE will clear the bit after updat-
ing the device address. Otherwise, when this bit is cleared to 0 , the SIE will update
the device address immediately after an address is written to the Address+Re-
mote_WakeUp Register (42H)
Default 0
This bit is used to indicate that some errors have occurred when accessing the FIFO0.
This bit is set by SIE and cleared by F/W.
Default 0
This bit is used to indicate that an OUT token (except for the OUT zero length) has
been received. The F/W clear the bit after the OUT data has been read. This bit will
also be cleared by the SIE after the next valid SETUP token is received.
Default 0
This bit is used to indicate that the current signal the USB is receiving from the PC
Host is IN token.
This bit is used to indicate that the SIE is transmitting NAK signal to the Host in re-
sponse to the PC Host IN or OUT token.
This bit is used to indicate there are CRCerror (bit=1). Firmware must do something to
save the device and keep it in good condition.
This bit is set by SIE and cleared by F/W.
End of transaction flag, normal status is 1. If suspend= 1 line & EOT= 0 indicates that
something is wrong in the USB Interface. Firmware in-charge must do something to
save the device and keep it in good condition.
This bit is used to control whether the USB interrupt is output to the MCU in NAK re-
sponse to the PC Host IN or OUT token.
1: has only USB interrupt, data is transmitted to the PC host or data is received from
the PC Host
0: always has USB interrupt if the USB accesses FIFO0
