23.3.3.1.3 CMD_FS_POWERUP: Power Up Frequency Synthesizer
Command ID number: 0x080C
CMD_FS_POWERUP is a radio operation command. In addition to the parameters listed in
the command structure contains the fields listed in
On start, the radio CPU powers up the frequency synthesizer and applies the register modifications given
in pRegOverride. If pRegOverride is NULL, no registers are overridden. The format of the override
structure is the same as the format for CMD_RADIO_SETUP (see
applicable to the synthesizer hardware are applied.
Running CMD_FS_POWERUP is mandatory before using any command that uses the frequency
synthesizer (and thus, the transmitter or receiver), unless the synthesizer has been powered up as part of
the radio setup. The radio must be set up using CMD_RADIO_SETUP or another setup command before
CMD_FS_POWERUP.
If the pointer in pRegOverride is invalid, the address or index is invalid, the length of an array is zero or is
too large. If another parameter in an entry is not permitted, the operation ends with the status
ERROR_PAR. If powering up the synthesizer fails, the command ends with ERROR_SYNTH_PROG as
the status. When otherwise finished, the command ends with DONE_OK as the status.

23.3.3.1.4 CMD_FS_POWERDOWN: Power Down Frequency Synthesizer
Command ID number: 0x080D
CMD_FS_POWERDOWN is a radio operation command that only takes the mandatory arguments listed
in Table 23-8. The command waits for the start trigger and then powers down the synthesizer. The act of
powering down not only stops the synthesizer, as is done with CMD_FS_OFF (see
at the end of certain other radio operation commands, but it also switches off analog modules.
After running CMD_FS_POWERDOWN, the synthesizer must be powered up again using
CMD_FS_POWERUP, or another command that powers up the synthesizer before it is used.
CMD_FS_POWERDOWN must always be run before the radio is powered down (for instance, when the
device is going into low-power modes).
When finished, the CMD_FS_POWERDOWN command ends with a DONE_OK status.
