/RST = L sets all registers to their default values. Exceptions are register bits CLKM_CTRL (reg-
ister 0x03, TRX_CTRL_0), refer to
117.
After releasing the reset pin (/RST = H) the wake-up sequence including an FTN calibration
cycle is performed, refer to
the TRX_OFF state is entered.

transceiver was not in SLEEP state.
The reset procedure is identical for all originating radio transceiver states except of state P_ON
and SLEEP state. Instead, here the procedure described in
after VDD” on page 34
If the radio transceiver was in SLEEP state, the XOSC and DVREG are enabled before entering
TRX_OFF state.
If register TRX_STATUS indicates STATE_TRANSITION_IN_PROGRESS during system initial-
ization until the AT86RF231 reaches TRX_OFF, do not try to initiate a further state change while
the radio transceiver is in this state.
Notes
The transition numbers correspond to
if not otherwise stated. See measurement setup in
• The reset impulse should have a minimum length t
• An access to the device should not occur earlier than t
• A reset overrides an SPI command request that might be queued.
