Sources of reference frequency
0 -> internal quartz oscillator (for XTAL or TCXO)
1 -> external signal applied on pin XTA (CMOS type signal, external clock)
Enable clkout
0 -> no signal provided on pin CLKOUT
1 -> Signal at reference frequency divided by 2, 4, 8,16, 32 provided on
CLKOUT (19.5 MHz down to 1.22 MHz)
Frequency of signal provided on CLKOUT:
000 -> 1.22 MHz
001 -> 2.44 MHz
010 -> 4.87 MHz
011 -> 9.75 MHz
others -> 19.5 MHz
use the transceiver with a crystal operating on its third overtone
0000 -> no resistor ( 3.8 MΩ)
0001 -> 1.48 kΩ
0 -> disabled
1 -> enabled
