FSK/OOK Description
PreambleDetectorOn
PreambleDetectorSize
PreambleDetectorTol
Enables Preamble detector when set to 1. The AGC settings
rw
0x01 supersede this bit during the startup / AGC phase.
* 0 Æ Turned off
1 Æ Turned on
rw
0x01
*
Number of Preamble bytes to detect to trigger an interrupt
00 Æ 1 byte
10 Æ 3 bytes
01 Æ 2 bytes
11 Æ Reserved
rw
0x0A Number or chip errors tolerated over PreambleDetectorSize.
* 4 chips per bit.
TimeoutRxRssi
Timeout interrupt is generated TimeoutRxRssi*16*T_bit after
rw 0x00 ^{switching to Rx mode if Rssi interrupt doesn’t occur (i.e.}
RssiValue > RssiThreshold)
0x00: TimeoutRxRssi is disabled
TimeoutRxPreamble
Timeout interrupt is generated TimeoutRxPreamble*16*T_bit after
rw 0x00 switching to Rx mode if Preamble interrupt doesn’t occur
0x00: TimeoutRxPreamble is disabled
TimeoutSignalSync
Timeout interrupt is generated TimeoutSignalSync*16*T_bit after
rw 0x00 the Rx mode is programmed, if SyncAddress doesn’t occur
0x00: TimeoutSignalSync is disabled
InterPacketRxDelay
unused
RcCalStart
rw
0x00
Additional delay before an automatic receiver restart is launched:
Delay = InterPacketRxDelay*4*Tbit
RC Oscillator registers
r
- unused
wt
0x00
Triggers the calibration of the RC oscillator when set. Always
reads 0. RC calibration must be triggered in Standby mode.
ClkOut
Selects CLKOUT frequency:
000 Æ FXOSC
001 Æ FXOSC / 2
rw
0x07
*
010 Æ FXOSC / 4
011 Æ FXOSC / 8
100 Æ FXOSC / 16
101 Æ FXOSC / 32
110 Æ RC (automatically enabled)
111 Æ OFF
PreambleSize(15:8)

0x00
Size of the preamble to be sent (from TxStartCondition fulfilled).
(MSB byte)
rw
0x03
Size of the preamble to be sent (from TxStartCondition fulfilled).
