CC3200例程中如 MAP_IntMasterEnable(); 等程序有没有说明文档呢 ？

 如题，CC3200例程中很多函数都是引用的外部声明，

extern tBoolean IntMasterEnable(void);
extern tBoolean IntMasterDisable(void);
extern void IntVTableBaseSet(unsigned long ulVtableBase);
extern void IntRegister(unsigned long ulInterrupt, void (*pfnHandler)(void));
extern void PRCMCC3200MCUInit(void);

extern unsigned long PRCMHIBRegRead(unsigned long ulRegAddr);
extern void PRCMHIBRegWrite(unsigned long ulRegAddr, unsigned long ulValue);
extern unsigned long PRCMCameraFreqSet(unsigned char ulDivider,
unsigned char ulWidth);

像以上这些都是不明白为什么的，请问是否有说明文档说明以上函数的作用还是怎么样 ？
