3.2.1.2 System Tick Timer
The System Tick Timer's clock source is always the core clock, FCLK. This results in the
following:
• The CLKSOURCE bit in SysTick Control and Status register is always set to select
the core clock.
• Because the timing reference (FCLK) is a variable frequency, the TENMS bit in the
SysTick Calibration Value Register is always zero.
• The NOREF bit in SysTick Calibration Value Register is always set, implying that
FCLK is the only available source of reference timing.

SysTick->CTRL|=0x04;//设置系统滴答时钟源为系统内核频率

参考Cortex-M3权威指南的137页，不同的是System Tick Timer's clock source is always the core clock
在SysTick->CTRL|=0x04;//设置系统滴答时钟源为系统内核频率，其他一样用，LOAD的是24位，注意溢出！！
