rw 0x00
rw 0x00
Mapping of pins DIO0 to DIO5
rw 0x00
rw 0x00 ^{See Table 23 for mapping in LoRa mode}
rw 0x00 _{See Table 27 for mapping in Continuous mode}
rw 0x00 ^{See table 28 for mapping in Packet mode}
rw 0x00 reserved. Retain default value
Allows the mapping of either Rssi Or PreambleDetect to the DIO
rw
0x00
pins, as summarized on Table 27 and Table 28
0 Æ Rssi interrupt
1 Æ PreambleDetect interrupt
Version register
r
0x22
Version code of the chip. Bits 7-4 give the full revision number;
bits 3-0 give the metal mask revision number.
Additional registers
r
- unused
Sets the floor reference for all AGC thresholds:
rw
0x13
AGC Reference [dBm] =
-174 dBm + 10*log(2*RxBw) + SNR + AgcReferenceLevel
SNR = 8 dB, fixed value
r
- unused
rw 0x0E Defines the 1st AGC Threshold
rw 0x05 Defines the 2nd AGC Threshold:
rw 0x0B Defines the 3rd AGC Threshold:
rw 0x0D Defines the 4th AGC Threshold:
rw 0x0B Defines the 5th AGC Threshold:
Bypasses the main state machine for a quick frequency hop.
rw
0x00
Writing RegFrfLsb will trigger the frequency change.
0 Æ Frf is validated when FSTx or FSRx is requested
1 Æ Frf is validated triggered when RegFrfLsb is written
rw 0x2E reserved
rw 0x00 reserved. Retain default value
Controls the crystal oscillator
rw 0x00 0 Æ Crystal Oscillator with external Crystal
1 Æ External clipped sine TCXO AC-connected to XTA pin
rw 0x09 Reserved. Retain default value.
rw 0x10 reserved. Retain default value
Enables the +20 dBm option on PA_BOOST pin
rw 0x04 0x04 Æ Default value
0x07 Æ +20 dBm on PA_BOOST when OutputPower = 1111
