PLL power down takes effect in Energy Detect mode
Power management mode:
00 = Normal mode (D0)
01 = Energy Detection mode (D2)
10 = soft Power Down mode (D3)
11 = Power Saving mode (D1)
N/A Do not change.
When the Energy Detect mode is on, this value is
used to control the minimum period that the no energy
