T_A = 25°C, VDD = 3.0 V if nothing else stated. All measurement results are obtained using the
CC2510EM reference designs ([1]).

See item 1, Figure 4. This is the shortest pulse that is
guaranteed to be recognized as a reset pin request.
Note: Shorter pulses may be recognized but will not lead to
complete reset of all modules within the chip.
See item 2, Figure 4. This is the shortest pulse that is
guaranteed to be recognized as an interrupt request. In PM2/3
the internal synchronizers are bypassed so this requirement
does not apply in PM2/3.
