Not used, always read as 0.
Power mode control. Writing a 1 to this bit forces CC2430 to enter
the power mode set by SLEEP.MODE (note that MODE = 0x00
will stop CPU core, no peripherals, activity when this bit is
enabled). This bit is always read as 0
All enabled interrupts will clear this bit when active and CC2430
will reenter PM0.

Description
Disable 32 kHz RC oscillator calibration
0 – 32 kHz RC oscillator calibration is enabled
1 – 32 kHz RC oscillator calibration is disabled.
The setting of this bit to 1 does not take effect until high-frequency
RC oscillator is chosen as source for system clock, i.e.
CLKCON.OSC set to 1.
Note: this bit is not retained in PM2 and PM3. After re-entry to PM0
from PM2 or PM3 this bit will be at the reset value 0
XOSC stable status:
0 – XOSC is not powered up or not yet stable
1 – XOSC is powered up and stable.
Note that an additionl wait time of 64 µs is needed after this bit has
been set until true stable state is reached.
High-frequency RC oscillator (HF RCOSC) stable status:
0 – HF RCOSC is not powered up or not yet stable
1 – HF RCOSC is powered up and stable
Status bit indicating the cause of the last reset. If there are multiple
resets, the register will only contain the last event.
00 – Power-on reset
01 – External reset
10 – Watchdog timer reset
High-frequency (32 MHz) crystal oscillator and High-frequency (16
MHz) RC oscillator power down setting. If there is a calibration in
progress and the CPU attempts to set this bit, the bit will be
updated at the end of calibration:
0 – Both oscillators powered up
1 – Oscillator not selected by CLKCON.OSC bit powered down
Power mode setting:
00 – Power mode 0
01 – Power mode 1
10 – Power mode 2
11 – Power mode 3
