如何进入DOzE模式并且如何唤醒,请指导,谢谢
Hi Zhangjie,
请参考TRM的2.6.1 Doze Mode.
设置Doze模式分为4步:
1. Software writes to the flash control registers to put all flash pumps to sleep.
2. Software writes to the clock source disable register (CSDIS) to disable the clock sources that are not needed.
3. Software writes to the clock domain disable register (CDDIS) to disable the GCLK (CPU clock), HCLK (system clock), VCLKP (peripheral VBUS clock), VCLK2 (peripheral VBUS clock2), VCLKA1 (asynchronous peripheral VBUS clock1), and VCLKA2 (asynchronous peripheral VBUS clock2).
4. Software “idles” the ARM core, then stops the core clock.
唤醒方式有如下几种:
Sleep mode supports the following wakeup (return to normal operation) methods:
• Any asynchronous wakeup interrupt
– RTI interrupt
– An external GIO Interrupt
– CAN message
– SCI or LIN message
• Power-on reset or system reset
具体的设置可否提供,谢谢
