CC1110Fx / CC1111Fx
CLKCON (0xC6) – Clock Control
Bit Name
Reset R/W Description
7
OSC32K
1
R/W 32 kHz clock oscillator select. The HS RCOSC must be selected as system
clock source when this bit is to be changed.
0
32.768 kHz crystal oscillator
1
Low power RC oscillator (32 – 36 kHz for CC1110Fx and 32 kHz for
CC1111Fx)
Note: This bit is not retained in PM2 and PM3. After re-entry to active mode
from one of these power modes this bit will be at the reset value 1.
6
OSC
1
R/W System clock oscillator select.
0
High speed crystal oscillator
1
HS RC oscillator
This setting will only take effect when the selected oscillator is powered up and
stable. If the high speed crystal oscillator is not powered up, it should be
enabled by setting SLEEP.OSC_PD to 0 prior to selecting it as source.If the HS
RCOSC is to be the source and it is powered down, setting this bit will turn it
on.
5:3 TICKSPD[2:0] 001
R/W Timer ticks output setting. The value of TICKSPD cannot be higher than
CLKSPD.
CLKCON.OSC=0
HS XOSC used as clock source
for system clock
CLKCON.OSC=1
Calibrated HS RCOSC used as
clock source for system clock

Clock speed setting. When a new CLKSPD value is written, the new setting is
read when the clock has changed.
