The definitions of the USB/PS2 status and control register (USC; 1AH) are as shown.
USC
Bits
R/W
Function
SUSP
0
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
changing of this bit.
RMWK
1
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.
URST
2
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 an
USB reset is occurred (The attached bus is USB) and an USB interrupt will be initial-
ized.
RESUME
3
R
USB resume indication. When the USB leaves suspend mode, this bit is set to 1
(set by SIE). This bit will appear 20ms waiting for MCU to detect. When the RE-
SUME is set by SIE, an interrupt will be generated to wake-up the MCU. In order to
detecting the suspend state, MCU should set 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 MCU is detecting the SUSP, the RESUME (causes
MCU to wake-up) should be remembered and token into consideration.
PS2DAI
4
R
Read only, USBD-/DATA input
PS2CKI
5
R
Read only, USBD+/CLK input
PS2DAO
6
W
Data for driving USBD-/DATA pin when work under 3D PS2 mouse function.
(Default= 1 )
PS2CKO
7
W
Data for driving USBD+/CLK pin when work under 3D PS2 mouse function.
(Default= 1 )
The USR (USB endpoint interrupt status register) register is used to indicate which endpoint is accessed and to select
serial bus (PS2 or USB) and A/D converter operation modes. The endpoint request flags (EP0IF, EP1IF, EP2IF and
EP3IF) are used to indicate which endpoints are accessed. If an endpoint is accessed, the related endpoint request
flag will be set to 1 and the USB interrupt will occur (if USB interrupt is enabled and the stack is not full). When the ac-
tive endpoint request flag is served, the endpoint request flag has to be cleared to 0 .
USR
Bits
R/W
Function
EP0IF
0
R/W
When this bit is set to 1 (set by SIE), it indicates the endpoint 0 is accessed and an
USB interrupt will occur. When the interrupt has been served, this bit should be
cleared by firmware.
EP1IF
1
R/W
When this bit is set to 1 (set by SIE), it indicates the endpoint 1 is accessed and an
USB interrupt will occur. When the interrupt has been served, this bit should be
cleared by firmware.
EP2IF
2
R/W
When this bit is set to 1 (set by SIE), it indicates the endpoint 2 is accessed and an
USB interrupt will occur. When the interrupt has been served, this bit should be
cleared by firmware.
EP3IF
3
R/W
When this bit is set to 1 (set by SIE), it indicates the endpoint 3 is accessed and an
USB interrupt will occur. When the interrupt has been served, this bit should be
cleared by firmware.
SPS2
4
R/W The PS2 function is selected when this bit is set to 1 . (Default= 0 )
SUSB
5
R/W The USB function is selected when this bit is set to 1 . (Default= 0 )
ADREF
6
R/W
The reference voltage of A/D converter is coming from the VDD and VSS of MCU
when this bit is set 1 . Otherwise, the reference voltage of A/D converter comes
from external PB6/VRL and PB7/VRH pins. (Default= 1 )
FIFO-cntl
7
W
For ICE only, 0 for FIFO read (Default= 0 ); 1 for FIFO write
