Looks like ST began implementing artificial intelligence into their chips. While other companies are starting from the brains, ST started from the other side, by creating very specific function register under TDR. Only future will show whether this is the correct approach.

Oh, and notice that TDR is write only and RDR is read only.

Nice thing is that if you are really looking for this error, it is properly indexed.

Hey, but there are no gray shaded areas (see note on bottom)

Oh yes, and pink-shaded areas show where unicorns do live. Don't tell me they don't.

From LPC824 datasheet, here

Just a tiny reminder that Siemens MCU guys were probably located in Germany, back in the 90's. In case control logik is not enough for you, there you have schadow latch.

Now this is what i call preliminary datasheet

Well, @Atmel Corporation eeer I meant @Microchip Technology gives us some great datasheets, like this one for Atmega32. I archived this one, just for reference.

The datasheet goes into details, like specifies the multimeter should be high impedant.

Not sure whether the multimeter should be pedant, pediment or impotent, I'd use my #Micro progmeter.

Be careful with step-down converters, your PCB can turn heartsick.

Oh my, that was sad story.
