上一篇里转载了一个版本的系统控制寄存器初始化函数，这里转载另一个版本的，发现两个版本的差异。

void InitSysCtrl(void)

{

// On F2812/F2810 TMX samples prior to rev C this initialization was

// required.  For Rev C and after this is no longer required

/*

//宏定义EALLOW来设置状态寄存器1的C6位

   EALLOW;

// On TMX samples, to get the best performance of on chip RAM blocks M0/M1/L0/L1/H0 internal
// control registers bit have to be enabled. The bits are in Device emulation registers.

   DevEmuRegs.M0RAMDFT = 0x0300;

   DevEmuRegs.M1RAMDFT = 0x0300;

   DevEmuRegs.L0RAMDFT = 0x0300;

   DevEmuRegs.L1RAMDFT = 0x0300;

   DevEmuRegs.H0RAMDFT = 0x0300;

//宏定义EDIS来清除状态寄存器1的C6位

   EDIS;

*/

   // Disable the watchdog

   DisableDog();

   // Initialize the PLLCR to 0xA

   InitPll(0xA);

   // Initialize the peripheral clocks

   InitPeripheralClocks();

}
