The experiment:
1) Learn SPCE061 PLL oscillator function and its application.
2) master the system clock unit P_SystemClock setting method.
3) familiar with the system clock and CPU clock frequency programming method.
Laboratory equipment:
1) with μ nSP ™ IDE emulation environment for PC machine.
2) μ nSP ™ 16 single-chip experiment box one.
3) an oscilloscope.
Experimental principle:
In SPCE061A inside, P_SystemClock (W) ($ 7013H) unit controls the system clock and CPU clock. By setting the unit B5-B7 bit can change the system clock frequency (Fosc = 20/24/32/40/49MHz) 0-2 position of the first "111" can make the CPU clock is stopped, the system switches to low standby power. In the standby state, by setting the unit can be switched on or off B4 32KHz bit real time clock. And by setting the unit B3 bit 32768Hz clock can automatically at the weak state of vibration or strong vibration. This experiment by choosing different Fosc frequency signal frequency or change
