Prop II question : Counters PWM, External Clock, and capture

In Prop II spec,
Attachment not found.

The counters have improved, but detail is lacking,
It says
["The counter modes now also feature quadrature encoder accumulation and automatic PWM generation."]
- so that means external edge counting, but to what Speed ?
'automatic PWM generation' suggests a proper compare/reload

I can see no mention of capture modes, but it does mention SIN and COS.
Surely capture is not overlooked ? 8 & 10 pin micros have capture ?

I was hoping this would define edges to 5ns and capture(time) external edges to a precision of 5ns, without software fudge gotcha's :(

    Yeah... the document just gives a rough idea of what is to come.

    The problem with 'rough ideas' and vague documents, is that any mistakes are invisible, until it is too late...
