BIT NAME FUNCTION
7:0 ident Read-only register used for identification purpose. The content of this register is always 0xA6.
BIT NAME FUNCTION
6 gp1bst
0 = Normal GPO1 output driver
1 = Extended driving capability on GPO1
5 pllbw
PLL bandwidth setting, low (0) = 300kHz or high (1) = 600kHz; 300kHz is recommended for fractional-N
and 600kHz for fixed-N (ASK mode only)
4:3 anshp[1:0]
Control time constants of the analog shaping (bias inductor connected to the ROUT pin)
anshp[1:0] Rise/fall time
00 ROUT open-circuited, 4Fs pulse extension present
01 nominal 3.0Fs rise/fall time
10 nominal 1.5Fs rise/fall time
11 no analog shaping, no 4Fs pulse extension
2 clksby Crystal clock output enable (1) while part is in standby mode
1 clkout Crystal clock output enable (1) on GPO1 output, gp1s[2:0] = 0x2
0 mode ASK (0) or FSK (1)
BIT NAME FUNCTION
7:5 ckdiv[2:0] 3-bit clock output frequency divider
