11.4 External ResetAn External Reset is generated by a low level on the RESET pin. Reset pulses longer than the minimum pulse width (see "System and Reset Characteristics" on page 324) will generate a reset, even if the clock is not running. Shorter pulses are not guaranteed to generate a reset.Table 29-12. Reset, Brown-out and Internal Voltage Characteristics(1)SymbolParameterMinTypMaxUnitstRST Minimum pulse width on RESET Pin2.5?s
It could just be a documentation error.

So my value of tRST = 300ns does not contradict the datasheet.Actually it's the maximum minimum. Because, tRST is "Minimum pulse width on /RESET Pin".So in the absence of minimum and typical, I would read that as the figure which is the minimum reset pulse. Notwithstanding that it contradicts the chart on page 422.
