我想让2410进入掉电模式,然后通过中断唤醒,在2410datasheet上有这么一段:
"In Power_OFF mode, only VDDi and VDDiarm will be turned off, which is controlled by PWREN pin.
If PWREN signal is active(H), VDDi and VDDiarm are supplied by an external voltage regulator. If PWREN pin is
inactive (L), the VDDi and VDDiarm are turned off."
还有这么一句:
"PWREN O 2.0V core power on-off control signal"--ver:1.0
"PWREN O 1.8V core power on-off control signal"--ver:1.2
第一段是说:PWREN的高低可以控制2410的掉电模式;
第二段是说:PWREN的控制给内核供电的电压是1.8v还是2.0v;
所以不明白在硬件上PEREN到底该怎么连了?
请知道的指教一下!谢谢! |
