And the maximum value of tRST is 2.5us (table 29-12). Typical and minimum values are not given. So my value of tRST = 300ns does not contradict the datasheet.
How is that value labeled? Why would there be a maximum pulse width? What happens to a processor when the maximum pulse width is exceeded (something I do every time I program an ATtiny processor)? Is it possible the person who wrote the document placed the value in the wrong column? That the value is the minimum pulse width rather than the maximum?
