Chapter 2 Clock Controller
2.3
Usage Demo
2.3.1 Clock Control
Control clock includes setting stabilization time, setting clock divide and setting clock mode.
Select clock has four values: main clock, sub clock, main CR clock, sub CR clock. The clock
stabilization time is changed by the CLOCK_TIME. First set the clock stabilization time,
second select what clock use as source clock and last set the clock divide.
For example, if you want set the main clock, select main clock mode and set the clock to
source/4, add the following function to you program.
//the sample code to control main clock
void clock_control(void)
{
Clock_Stabilization_Time_Set(FCH_14_DIV);
//set main clock stabilization time
Clock_Set_CPU_Clock(Main_Clock) ;
// set main clock
Clock_Set_Divide(Clock_Div_4);
// set the clock to source/4
}
2.3.2 Get Clock Status
When you want to know the clock mode and clock divide status, you can use uchar
Clock_Get_CPU_Clock_status(void) and uchar Clock_Get_Divide_Status(void) function.
The sample as:
Void get_clock_status(void)
{
uchar state,state1;
state = Clock_Get_CPU_Clock_status ();
//return run clock mode
state1 = Clock_Get_Divide_Status ();
//return the clock divide status
}

Usage Demo
6.3.1 External Interrupt
If you want to use the interrupt, it will relate with set interrupt, level and interrupt control.
When you want to set the external interrupt, you can use the External_Interrupt(int
Int_name,uchar State) function. Set the interrupt level use the External_Interrupt_Level(int
Int_name_Level) function. Use the External_Interrupt_Request(int Int_name_request)
function can get the interrupt request and clear it.
The sample as:
Void Interrupt_function(void)
{
External_Interrupt_Level(Ext_Int2_Level_0); //set the extern interrupt and level 0
External_Interrupt(Ext_Int2,Interrupt_Enable);//enable the extern 2 interrupt
}
__interrupt void external_int2( void )
{
……
External_Interrupt_Request(Ext_Int2_Request);// get the interrupt request and clear it
}
6.3.2 Other Interrupt
When you want to set other interrupt, you can use the interrupt set function, interrupt level
set function and interrupt control function.
The sample as:
