Question

Misprints in RM0090 Figure100 and Figure148?

Here the UIF waveform shifted to high when counter register equaled to 0x02. Isn’t it supposed to shift at the moment the UEV is set? Figure148 also has this problem. And I traced back to the earlier versions. As far as I can reach, the figures were good until rev11, and they were changed since rev17 or earlier.

It seems the UIF is updated when counter register is 02. So UIF maybe configurable when counter register setting value

Sorry, I don’t get it. According to the manual, the UIF can only shift from 0 to 1 when one of these things happen: 1. counter overflow; 2. counter underflow; 3. an update event. But the figure I posted doesn’t match any of these cases.

Hello ​@zipeilu;

 

It is a typo in Figures 100 and 148, the UIF waveform should be high at the same moment the UEV is set.

 

Thank you.
