2.1.1 Register Overrides

The MCE_RFE override ⁽¹⁾needs to be modified when running the IQ Dump patch. Table 2-2 shows how this should be done. In addition, there is one other override necessary to add when running the patch.

Table 2-2 Overrides and Mode of Operation

Override	Description
MCE_RFE_OVERRIDE(1,0,2,1,0,0) // CC13x0 MCE_RFE_OVERRIDE(1,0,2,0,4,0) // CC13x2	Setting the mode of operation to IQFifoBlind
MCE_RFE_OVERRIDE(1,0,3,1,0,0) // CC13x0 MCE_RFE_OVERRIDE(1,0,3,0,4,0) // CC13x2	Setting the mode of operation to IQFifoSync
(uint32_t)0x001082C3	Set to avoid internal FIFO overflow
HW_REG_OVERRIDE(0x52B4, 0x070D) (optional) // CC13x0 HW_REG_OVERRIDE(0x5328, 0x070D) (optional) // CC13x2	Enable built-in test pattern. Should only be included when testing the patch. For more details, see Section 3 (optional).

In addition you need to include the patch and update the TI_RTOS RF Mode Object:

CC13x0:

#include DeviceFamily_constructPath(rf_patches/rf_patch_cpe_genfsk.h)
#include DeviceFamily_constructPath(rf_patches/rf_patch_mce_iqdump.h)
#include DeviceFamily_constructPath(rf_patches/rf_patch_rfe_genfsk.h)
#include "smartrf_settings.h"
// TI-RTOS RF Mode Object
RF_Mode RF_prop =
{
    .rfMode = RF_MODE_PROPRIETARY_SUB_1,
    .cpePatchFxn = &rf_patch_cpe_genfsk,
    .mcePatchFxn = &rf_patch_mce_iqdump,
    .rfePatchFxn = &rf_patch_rfe_genfsk,
};

CC13x2:

#include DeviceFamily_constructPath(rf_patches/rf_patch_cpe_prop.h)
#include DeviceFamily_constructPath(rf_patches/rf_patch_mce_iqdump.h)
#include "smartrf_settings.h"
// TI-RTOS RF Mode Object
RF_Mode RF_prop =
{
    .rfMode = RF_MODE_AUTO,
    .cpePatchFxn = &rf_patch_cpe_prop,
    .mcePatchFxn = &rf_patch_mce_iqdump,
    .rfePatchFxn = 0,
};

1. Only one MCE_RFE can be present in the override list.
