Command ID number: 0x080D
CMD_FS_POWERDOWN is a radio operation command that only takes the mandatory arguments listed in Table 26-9. 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 Section 26.3.3.1.6) or 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.
