 * If Studio is allowed to use the CTUNE value from EEPROM on Silicon Labs radio board,
 * it will store it in the User page memory on the MFG_CTUNE_ADDR address.
 * If not, for example user already storing a value there, then the MFG_CTUNE_EN
 * must be set to 0, to avoid wrong value to be read out.
 * Studio can only read out the CTUNE value from the EEPROM if that is a
 * Silicon Labs radio board.
 * Please verify that CTUNE value is stored at the MFG_CTUNE_ADDR of
 * the User page, if want to overwrite the default MFG_CTUNE_EN define
 * for self use on custom boards.
