Timeout
defines the timeout of the second mode, after the automatic transition. It is expressed in periods of the
32.768kHz RTC. The maximum timeout value coresponds to 512 s.
0x000000
disables the timeout function.
If the AutoTxRx mode is enabled, and a
SetTx
( ) command is sent to the device, the device will go to RX mode after TX_DONE
and the given delay.
Timeout
is used as the
RxTimeout
of the auto RX.
If the AutoTxRx mode is enabled, and a
SetRx
( ) command is sent to the chip, the chip will go to Tx mode after RX_DONE
and the given delay.
Timeout
is used as the
TxTimeout
of the auto Tx.
If a RxDutyCycleMode is started, this mode is not used.
7.2.5
SetRxTxFallbackMode
The command
SetRxTxFallbackMode( )
defines in which mode the device goes after a packet transmission or a packet
reception.
•
FallbackMode
values
:
0x01: Standby RC mode (default value).
0x02: Standby Xosc mode
0x03: FS mode
If a
RxDutyCycle
is started or an
AutoRxTx
is configured, this mode is not used.
The fallback mode is also used for RxDutyCycleMode after the RX_DONE interrupt, or for an AutoRxTx after the RX to TX, or
TX to RX sequence is completed.
7.2.6 SetRxDutyCycle
The command
SetRxDutyCycle( )
periodically opens RX windows. Between RX windows, the device goes in Sleep mode (with
retention).
