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 .
Bit No.
Label
R/W
Function
0
EP0IF
R/W
When this bit is set to 1 (set by 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 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 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.
3
EP3IF
R/W
When this bit is set to 1 (set by SIE), it indicates the endpoint 3 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 )
6
ADREF
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 )
7
FIFO-cntl
W
For ICE only, 0 for FIFO read (Default= 0 ); 1 for FIFO write
USR (1BH) Register
There is a system clock control register implemented to select the clock used in the MCU. This register consists of USB
clock control bit (USBCKEN), second suspend mode control bit (SUSP2) and system clock selection (SYSCLK).
Bit No.
Label
R/W
Function
2~0
Led_on Period R/W
To define low pulse period of IRPT (PC0) for mouse hardware function.
The time base is 31.25 s (1/32kHz). Default value is 000.
000: 2 base
001: 3 base
010: 5 base
011: 9 base
100: 17 base
101: 33 base
110: 65 base
111: 127 base
3
USBCKEN
R/W
USB clock control bit. When this bit is set to 1 , it indicates that the USB clock is
enabled. Otherwise, the USB clock is turned-off. (Default= 0 )
4
SUSP2
R/W
This bit is used for decreasing power consumption in suspend mode.
In normal mode clean this bit=0 (Default= 0 )
In HALT mode set this bit=1 for decreasing power consumption.
5
R/W Undefined, should be cleared to 0
6
SYSCLK
R/W
This bit is used to specify the system oscillator frequency used by MCU. If a
6MHz crystal oscillator or resonator is used, this bit should be set to 1 . If a
12MHz crystal oscillator or resonator is used, this bit should be cleared to 0 (de-
fault).
7
HWKUPSB
R/W
Hardware HALT mode wake-up detect circuit active under power down mode.
Low active.
0 : WDT timer overflow will wake-up MCU system
1 : WDT timer overflow will start hardware wake-up detect circuit but not
wake-up MCU system.
SCC (1CH) Register
