c++ - 用魔术包唤醒 LPC1768

Question

我正在尝试使用魔术包将 LPC1768 从睡眠模式中唤醒。但不知何故，设备没有醒来。

仅供参考：当我启用“Wakeup at any packet”选项时，设备会唤醒。

我的错误在哪里？

//Interrupt Enable Register
int *IntEnable = (int*) 0x50000FE4;
#define WakeupIntEn 13  

//Receive Filter Control Register
int *RxFilterCtrl = (int*) 0x50000200;
#define RxFilterEnWoL       13      
#define MagicPacketEnWoL    12

int main() {

NVIC_EnableIRQ(ENET_IRQn);
NVIC_SetVector(ENET_IRQn, (uint32_t) MyEthernetHandler);

*IntEnable |= (1 << WakeupIntEn);
*RxFilterCtrl = (1 << MagicPacketEnWoL);

__WFI();

}
