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.
