datasheet 中 assert 和 deassertion 含义
assert: set a signal to its ”active” state.
例如一个信号是高有效,那么assert就是把它拉高。如果一个信号是低有效,那么assert就是把它拉低。
deassertion: set a signal to its “inactive” state
If a signal is active-low, “asserting” it means setting it low and “deasserting” it means setting it high.
举个例子:
VDDQ may ramp up after SLP_S3# de-assertion due to VR ramp timing and configuration
这意思是说:vddq要在SLP_S3#拉高之后才输出。

因为datasheet大部分都是英文的,
所以我们有必要去理解清楚,
不要觉得无所谓,谢谢!
