在首次进入HALT，测试功耗是0.82ua,awu唤醒后再次进入HALT，测试功耗是1.35ma,这是什么情况？
void GPIO_LowPower_Config(void)
{
GPIO_Init(GPIOA, GPIO_Pin_All, GPIO_Mode_Out_PP_High_Slow);
GPIO_Init(GPIOB, GPIO_Pin_All, GPIO_Mode_Out_PP_High_Slow);
GPIO_Init(GPIOC, GPIO_Pin_All, GPIO_Mode_Out_PP_High_Slow);
GPIO_Init(GPIOD, GPIO_Pin_All, GPIO_Mode_Out_PP_High_Slow);
}
void Enter_Halt(void)
{
AWU_DeInit();
AWU_Cmd(ENABLE);
AWU_Init(AWU_Timebase_30s);
GPIO_LowPower_Config();
asm("halt");
}
void main(void)
{
asm("sim"); //关中断
GPIO_LowPower_Config();
CLK_DeInit();
CLK_MasterPrescalerConfig(CLK_MasterPrescaler_HSIDiv2); //时钟8分频，2MHz
CLK_PeripheralClockConfig(CLK_Peripheral_AWU, ENABLE);
enableInterrupts();/* 开所有中断 */
Enter_Halt();
while (1)
{
delay_ms(1);
Enter_Halt();
}
}
INTERRUPT_HANDLER(AWU_IRQHandler,4)
{
/* In order to detect unexpected events during development,
it is recommended to set a breakpoint on the following instruction.
*/
AWU->CSR = AWU->CSR;
}
