关于IWDG与HALT模式问题
项目应用过程中进行以下初始化IWDG后，进入HALT模式，其Option bytes选其Independant Watchdog is stopped in HATL/ACTHAL mode ,单片机（STM8L151K4T6）老是自动复位，敬请各位帮忙看一下，谢谢！-------------------------IWDG初始化----------------------
/* Enable IWDG (the LSI oscillator will be enabled by hardware) */
IWDG_Enable();
/* IWDG timeout equal to 214 ms (the timeout may varies due to LSI frequency
dispersion) */
/* Enable write access to IWDG_PR and IWDG_RLR registers */
IWDG_WriteAccessCmd(IWDG_WriteAccess_Enable);
/* IWDG configuration: IWDG is clocked by LSI = 38KHz */
IWDG_SetPrescaler(IWDG_Prescaler_128);
/* IWDG timeout equal to 214.7 ms (the timeout may varies due to LSI frequency dispersion) */
/* IWDG timeout = (RELOAD_VALUE + 1) * Prescaler / LSI
= (254 + 1) * 128 / 38 000
= 858.9 ms */
IWDG_SetReload((uint8_t)RELOAD_VALUE); //RELOAD_VALUE=254
/* Reload IWDG counter */
IWDG_ReloadCounter();
----------------------主函数--------------------------------------
void main(void)
{
.............
while(1)
{
#ifdef IWDG_ENABLE
IWDG_ReloadCounter();
#endif
BoardScanKey();
__wait_for_interrupt();
}
}
麻烦各位帮忙看一下，谢谢！
