pins should therefore be set as outputs or
pulled high/low externally to avoid leakage
current.
To save power, the radio should be turned
off when it is not used.

USB Enable (CC2511Fx). This bit is unused for CC2510Fx.
0 – USB Disabled
1 – USB Enabled
26/48 MHz Crystal oscillator stable status:
0 – oscillator is not powered up or not yet stable
1 – oscillator is powered up and stable
High speed RC oscillator stable status:
0 – oscillator is not powered up or not yet stable
1 – oscillator is powered up and stable
Reserved.
XOSC and HS RCOSC power down setting. The bit is cleared if
the CLKCON.OSC bit is toggled. Also, if there is a calibration in
progress and the CPU attempts to set the 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
Sleep mode setting:
00 – Power mode 0
01 – Power mode 1
10 – Power mode 2
11 – Power mode 3
