Table 15-2. Mode Transition Time
Entry to
The signal on the RFCTLEN pin being at the low level for two cycles of the RF slow clock
after the power-supply voltage has 1.6 V from 0 V
Two cycles of the RF slow clock following a transition of the signal on the RFCTLEN pin
from the low to the high level
Two cycles of the RF slow clock following a transition of the signal on the RFCTLEN pin
from the high to the low level
Two cycles of the RF slow clock following a transition of the signal on the CE_RF pin from
the low to the high level
After entering STANDBY_RF mode, this mode must be retained for at least the oscillation
stabilization time [550 µs + α (where α differs with the oscillator)].
Two cycles of the RF slow clock following a transition of the signal on the CE_RF pin from
the high to the low level
Two cycles of the RF slow clock following a transition of the signal on the RFCTLEN pin
from the high to the low level
(4 x 1/RF slow clock + 1/RF base clock x 6) following a transition of the signal on the
RESET_RF internal pin from the low to the high level
Low width (min.)
After entering STANDBY_RF mode, this mode must be retained for at least the oscillation
stabilization time [550 µs + α (where α differs with the oscillator)].
Two cycles of the RF slow clock following a transition of the signal on the RFCTLEN pin
from the high to the low level
Within a period of one cycle of the RF slow clock + (1 µs)
Within a period of one cycle of the RF base clock following a generation of the interrupt
Within a period of one cycle of the RF slow clock + (1 µs)
Within a period of one cycle of the RF base clock following a generation of the interrupt
1 µs
After entering SETUP_RF mode, the duration period is 11 µs.
150 µs
After entering RF transmission mode, the duration period is max. 376 µs and min. 80 µs.
150 µs
After entering RF reception mode, the duration period is min. 80 µs.
