7.11 Control AC Characteristics
TA = 25 °C, VDD = 3.0 V if nothing else stated. All measurement results are obtained using the
CC1110EM 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.

tSYSCLK
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.
