20–23 pRegOverride W registers to override. If NULL, no override is
used.
On start, the radio CPU sets up parameters for the operational mode given by mode.radioMode, with the
modifications given in pRegOverride, a pointer to a structure containing override values for certain
hardware registers, radio configuration controlled by the radio CPU, and protocol-related variables. If
pRegOverride is NULL, no registers are overridden.
Running CMD_RADIO_SETUP or another radio setup command is mandatory before using any command
that uses the receiver, transmitter, or frequency synthesizer. If the RF core is reset, CMD_RADIO_SETUP
must be re-run.
The loDivider field decides which frequency range the radio can use. For a more accurate value and to
improve the accuracy of the receiver intermediate frequency, a center frequency override may be used as
described in Table 23-20.
The txPower parameter is stored and is applied every time transmission of a packet starts, to set an
output power with temperature compensation. This setting can be changed later with the command
CMD_SET_TX_POWER, where the details of the parameter are described.
The override value structure is a string of 32-bit entries provided by TI or produced by SmartRF Studio.
