Description
Transmitter output power:
00 -> 0 dBm
01 -> 5 dBm
10 -> 10 dBm
11 -> 15 dBm
Inhibition of the modulation in transmitter mode:
0 -> modulation
1 -> no modulation
Pre-filtering of the bit stream in transmitter mode:
0 -> no filtering
1-> data shaping filter enabled
RESERVED
0 -> bit sync in normal environment
1-> bit sync in noisy environment
RESERVED
Description
Transmission stopped ( IRQ source)
0 -> Start transmission when the FIFO is full
1 -> Start transmission when FIFO is not empty (/fifoempty = ‘1’)
Enable interrupt RSSI_irq when RSSI_thr is reached:
0 -> no interrupt generated
1 -> interrupt allowed
Detection of a signal above RSSI_thr (IRQ source)
0 -> signal power lower than the threshold defined by RSSI_thr.
1 -> signal power equal or greater than the threshold defined by RSSI_thr
Writing ‘1’ clear RSSI_signal_detect
RSSI threshold for interrupt
00 -> input power ≥ VTHR1
01 -> input power ≥ VTHR2
10 -> input power ≥ VTHR3
11 -> input power ≥ VTHR3
all bit rates defined by Br are available
frequency deviations given in Table 11 are available
Bit synchronizer on/off:
Description
0 -> ON
1 -> OFF
Bandwidth of the base band filter(SSB): must be ≥ Freq_dev + Br/2
00 -> 10 kHz
01 -> 20 kHz
10 -> 40 kHz
11 -> 200 kHz
Forces the bandwidth of the base band filter to its maximum value
