似乎有必要将SysMD(PMPM0)清除,以使定时器1在SoSC上的外部晶体睡眠期间正常工作。然而,在数据表P93上(图7.1),看起来SOSC可以直接路由到外设而不经过SysMCD锁存器。有什么意见吗?
以上来自于百度翻译 以下为原文 It seems that it's necessary to leave SYSCMD (in PMD0) clear for timer 1 to work properly during sleep from an external crystal on SOSC. Yet on p93 of datasheet (figure 7.1) it looks as though SOSC can route to the peripherals directly without passing through the SYSCMD latch? Any comments? |

同步启动了吗?然后,SOSC时钟不能计时,否则,提交一张票。我同意,似乎Fosc不应该为Time1跑去跑掉SOSC。
以上来自于百度翻译 以下为原文 Do you have synchronization turned on? Then the SOSC clock wouldn't make it to the timer. Otherwise, submit a ticket. I agree, it doesn't seem that Fosc should have to be running for Timer1 to run off of SOSC. |

是的,NoTySyc位已被设置。我将继续在我的代码中进行拨号。也许还有别的…
以上来自于百度翻译 以下为原文 Yes, the not_sync bit is set. I'll continue to poke around in my code. Might still be something else... |

从数据表中的睡眠期间21.8秒1 / 3/5的操作的底部,同步比特对睡眠模式中的SOSC没有影响(“无论同步比特设置如何,次级振荡器将继续在睡眠模式下工作”)。方框图21-1显示了在右下角的同步块的休眠输入,支持这一点。
以上来自于百度翻译 以下为原文 Bottom of section 21.8 Timer1/3/5 Operation During Sleep from the datasheet states the SYNC bit has no effect on the SOSC in Sleep mode ("The secondary oscillator will continue to operate in SLEEP mode regardless of the SYNC bit setting"). The block diagram Figure 21-1 shows a Sleep input to the Synchronize block in the lower right hand corner, supporting this. |

“杰克@ KkStack”我理解了21.8段,这意味着晶体振荡器将继续在睡眠期间供电,不管同步位设置,但除非设置为NoTySalc,否则定时器1将不计数。
以上来自于百度翻译 以下为原文 @jack@kksound I understood the 21.8 paragraph to mean that the Crystal Oscillator will continue to be powered during sleep regardless of the sync bit setting, but that Timer 1 will not count unless it's set to not_sync. |

由于同步位对次级振荡器没有其他影响,所以我认为同步化块在睡眠期间被禁用,这是有意义的,因为外部时钟与非操作内部振荡器的同步是愚蠢的。这应该很容易用实际的硬件来验证(此时我没有访问硬件)。
以上来自于百度翻译 以下为原文 As the SYNC bit has no other effect on the secondary oscillator I think the meaning is that the Syncronization block is disabled during SLEEP, this makes sense as synchronization of the external clock to a non-operational internal oscillator is silly. This should be easy to verify with actual hardware (I do not have access to hardware at this time). |
