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).

Function
Led_on Period
2~0
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
USBCKEN

R/W
USB clock control bit. When this bit is set to 1 , it indicates that the USB clock is en-
abled. Otherwise, the USB clock is turned-off. (Default= 0 )
SUSP2
4
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
SYSCLK
6
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 (default).
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.
The A/D converter implemented in the MCU is a 6-channel 8-bit A/D converter. The reference voltage (high reference
voltage and low reference voltage) can be selected as coming from external pins (PB6/VRL and PB7/VRH) or internal
power supplies of MCU (VDD and VSS). The VRLand VRH are used to set the minimal and maximal boundaries of the
full-scalerangeoftheA/Dconverter.Ifananaloginputs,VRLorVRHisnotusedforA/Dconversion,italsocanbeused
as a general purpose I/O line. The ADSC (A/D converter status and control register) register is used to set the configu-
rations and A/D clock sources of A/D converter and control the operation of A/D converter.

These 3 bits are use to select one of eight A/D converter channels for the conversion. The
A/D converter input channels AN0~AN5 are pin-shared with PB0~PB5. PB6/VRL and
PB7/VRH are used for the A/D converter reference inputs. ACS2,ACS1,ACS0 :
