CCB<15:11>: Command Code bits
The command code bits ( 10010b ) are serially sent to the microcontroller to identify the bits to be
written in the RXCREG .
FINTDIO: Function Interrupt/Data Indicator Output bit
Sets the pin 16 function as the DIO or interrupt.
1 = DIO output
0 = INT input
DIORT<1:0>: Data Indicator Output Response Time bits
If pin 16 is selected as DIO, these bits set the response time within which the transceiver detects and
indicates the incoming synchronous bit pattern, and issues an interrupt to the host microcontroller.
11 = Continuous
10 = Slow
01 = Medium
00 = Fast
RXBW<2:0>: Receiver Baseband Bandwidth bits
These bits set the bandwidth of demodulated data. The bandwidth can accommodate different data
rates and deviations during frequency keying.
111 = Reserved
110 = 67 kHz
101 = 134 kHz
100 = 200 kHz
011 = 270 kHz
010 = 340 kHz
001 = 400 kHz
000 = Reserved
RXLNA<1:0>: Receiver LNA Gain bits
These bits, when set to different values, can accommodate environments with high interferences. The
LNA gain also affects the true RSSI value.
11 = -20 dB
10 = -14 dB
01 = -6 dB
00 = 0 dB
