S3C2410A 启动代码的掉电唤醒处理是怎么回事啊？
ARM的启动代码里，进入ResetHandler，然后进行一系统的初始化：看门狗，中断屏蔽，系统时钟初始化后，如果是掉电模式唤醒则进入掉电唤醒检测，是则进行掉电唤醒处理，处理完后又怎样回到进入掉电模式的呢，就是这几句：ldr r1 ,=GSTATUS3ldr r0, mov pc,r0 ，执行完后程序会到哪里去呢？。。ResetHandler

bne WAKEUP_POWER_OFF 如果是则进入WAKEUP_POWER_OFF

ldr r1,=GSTATUS3 ;GSTATUS3 has the start address just after POWER_OFF wake-up
ldr r0,
mov pc,r0 程序到了这里，然后程序会到哪里去呢？？？？？？
