MCU can communicate with endpoint FIFO by setting the corresponding registers, of which address is listed in the fol-
lowing table. After reading current data, next data will show on after 2 s. using to check endpoint FIFO status and re-
sponse to MISC register, if read/write action is still going on.

There are some timing constrains and usages illustrated here. By setting the MISC register, MCU can perform reading,
writing and clearing actions. There are some examples shown in the following table for endpoint FIFO reading, writing
and clearing.

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
changing 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 a
USB reset is occurred (The attached bus is USB) and a USB interrupt will be initial-
ized.
3
RESUME
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 RESUME
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 taken into consideration.
4
PS2DAI
R
Read only, USBD-/DATA input
5
PS2CKI
R
Read only, USBD+/CLK input
6
PS2DAO
W
Data for driving USBD-/DATA pin when work under 3D PS2 mouse function.
(Default= 1 )
7
PS2CKO
W
Data for driving USBD+/CLK pin when work under 3D PS2 mouse function.
(Default= 1 )
USC (1AH) Register
