There is a system clock control register implemented to select the clock used in the MCU. This register consists of the
USBclockcontrolbit(USBCKEN),secondsuspendmodecontrolbit(SUSP2)andsystemclockselection(SYSCLK).
Bit No.

Undefined, should be cleared to 0
3
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 )
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
PS2_flag
R/W
This flag is used to show the MCUis under PS2 mode. (Bit=1)

6
SYSCLK
R/W
This bit is used to specify the system oscillator frequency used by the 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).
