The definitions of the USB/PS2 status and control register (USC; 1AH) are as shown.
Bit No.
Label
R/W
Function
0
SUSP
R
Read only, USB suspend indication. When this bit is set to 1 (set by SIE), it indi-
cates the USB bus enters suspend mode. The USB interrupt is also triggered on any
changes of this bit.
1
RMWK
W
USB remote wake up command. It is set by MCU to force the USB host leaving the
suspend mode. When this bit is set to 1 , 2 s delay for clearing this bit to 0 is
needed to insure the RMWK command is accepted by SIE.
2
URST
R/W
USB reset indication. This bit is set/cleared by USB SIE. This bit is used to detect
which bus (PS2 or USB) is attached. When the URST is set to 1 , this indicates that
a USB reset has occurred (the attached bus is USB) and a USB interrupt will be ini-
tialized.
3
RESUME
R
USB resume indication. When the USB leaves the suspend mode, this bit is set to
1 (set by SIE). This bit will appear 20ms waiting for the MCU to detect. When the
RESUME is set by the SIE, an interrupt will be generated to wake-up the MCU. In or-
der to detect the suspend state, the MCU should set the USBCKEN and clear
SUSP2 (in SCC register) to enable the SIE detecting function. The RESUME will be
cleared while the SUSP is going 0 . When the MCU is detecting the SUSP, the RE-
SUME (wakes-up the MCU ) should be remembered and taken into consideration.

(Default= 1 )
USC (1AH) Register
The USR (USB endpoint interrupt status register) register is used to indicate which endpoint is accessed and to select
the serial bus (PS2 or USB). The endpoint request flags (EP0IF, EP1IF and EP2IF) are used to indicate which end-
points are accessed. If an endpoint is accessed, the related endpoint request flag will be set to 1 and the USB inter-
rupt will occur (if the USB interrupt is enabled and the stack is not full). When the active endpoint request flag is served,
the endpoint request flag has to be cleared to 0 .
Bit No.
Label
R/W
Function
0
EP0IF
R/W
When this bit is set to 1 (set by the SIE), it indicates the endpoint 0 is accessed and
a USB interrupt will occur. When the interrupt has been served, this bit should be
cleared by firmware.
1
EP1IF
R/W
When this bit is set to 1 (set by the SIE), it indicates the endpoint 1 is accessed and
a USB interrupt will occur. When the interrupt has been served, this bit should be
cleared by firmware.
2
EP2IF
R/W
When this bit is set to 1 (set by the SIE), it indicates the endpoint 2 is accessed and
a USB interrupt will occur. When the interrupt has been served, this bit should be
cleared by firmware.

4
SPS2
R/W
The PS2 function is selected when this bit is set to 1 . (Default= 0 )
5
SUSB
R/W
The USB function is selected when this bit is set to 1 . (Default= 0 )
7
USB_flag
R/W
This flag is used to show the MCUis in USB mode. (Bit=1)
