I am currently working on a design using the CC1352P7 and do not need to utilize the TX_20DBM_P and TX_20DMB_N pins (pins 5 and 6). Looking in the data sheet, these two pins are not listed under section 6.3 "Connections for Unused Pins and Modules." If these two pins are not being used, should they be grounded or NC? Or is there another solution?
