Alternatively the power calibration can be done immediately after programming of each module
using the SPI host controller interface, using the
CAL_SET_DATA
function. This option is useful if
the same image will be used in multiple equipment, of which some have the power turned down
further than the max allowed power level to save current consumption, however it requires a
host processor.

Programming
The desired application image can be programmed into the module either using the PurePath
TM
software and the included CC-Debugger. Or the PurePath
TM
software can be used to create the
desired image, which is saved and the integrator can use an in-house developed production
programmer to upload the image.
If developing an in-house programmer there are a few things to consider to successfully
program the CC8520 chip. Programming procedure:
// Enter the bootloader
BOOT_RESET();
BL_UNLOCK_SPI();
Check SWR Proceed only if SWR matches required value (Reset device and Restart
programming again)
// Erase the flash
