各位大神，我现在需要定时比如5分钟去做一件事情，分钟中断进入一次，5次分钟中断就可以去执行任务，同时我在五分钟到的时候去读了RTC，现在出现问题，5分钟到了，进入中断后，又再次进入了中断，不知什么原因
RTC初始化
void rtc_init(void)
{
RTCCTL01 = RTCTEVIE + RTCSSEL_0 + RTCMODE;
RTCYEAR = 0x2016; // Year = 0x2010
RTCMON = 0x09; // Month = 0x04 = April
RTCDAY = 0x05; // Day = 0x05 = 5th
RTCDOW = 0x01; // Day of week = 0x01 = Monday
RTCHOUR =0x10; // Hour = 0x10
RTCMIN = 0x32; // Minute = 0x32
RTCSEC = 0x45; // Seconds = 0x45
}
读RTC
void read_rtc_time(void)
{
for(;RTCCTL01&RTCRDY;) _NOP(); // 等待RTC有效
for(;RTCCTL01&RTCRDY;) _NOP(); // 等待RTC有效
temp_context.Year=RTCYEAR-2000;
temp_context.Month=RTCMON;
temp_context.Day=RTCDAY;
temp_context.Hour=RTCHOUR;
temp_context.Minute=RTCMIN;
temp_context.Second=RTCSEC;
}
