CC2640R2F: CC2640R2F-CC2592 EMK Differential or Single Ended RF?

Hi,

    Using the TIDC-CC2650-CC2592-EMK as reference, we replace the CC2650 with CC2640R2F and had the PCB board done. At the board file I need to set the RF Front End and Bias configuration define. Since I used the Simple Peripheral the define is set below for Differential RF and internal biasing  (default for CC2640R2 LaunchPad). But reviewing the schematic diagram It seems more like Single-Ended RF. What define should I set at the board file?

/*
 *  ============================================================================
 *  RF Front End and Bias configuration symbols for TI reference designs and
 *  kits. This symbol sets the RF Front End configuration in ble_user_config.h
 *  and selects the appropriate PA table in ble_user_config.c.
 *  Other configurations can be used by editing these files.
 *
 *  Define only one symbol:
 *  CC2650EM_7ID    - Differential RF and internal biasing
                      (default for CC2640R2 LaunchPad)
 *  CC2650EM_5XD    – Differential RF and external biasing
 *  CC2650EM_4XS    – Single-ended RF on RF-P and external biasing
 *  CC2640R2DK_CXS  - WCSP: Single-ended RF on RF-N and external biasing
 *                    (Note that the WCSP is only tested and characterized for
 *                     single ended configuration, and it has a WCSP-specific
 *                     PA table)
 *
 *  Note: CC2650EM_xxx reference designs apply to all CC26xx devices.
