5.22 Configuration Registers

The configuration of the CC1020 device is done by programming the 8-bit configuration registers. The configuration data based on selected system parameters are most easily found by using the SmartRF Studio software. Complete descriptions of the registers are given in Section 5.22.1. After a RESET is programmed, all the registers have default values. The TEST registers also get default values after a RESET, and should not be altered by the user.

TI recommends using the register settings found using the SmartRF Studio software. These are the register settings that TI specifies across temperature, voltage, and process. Check the TI web site for regularly updates to the SmartRF Studio software.
