CC1312R: VDDR suggestion, GPIO for boot, and confirmation of Balun

  1. How should we power VDDR?  There is an external DCDC that is dedicated to the CC1312 already (the input voltage is 24V, and this DCDC brings it down to 3.3V for the CC1312).  I saw one suggestion was just to hook the 3.3V to VDDR, but I also saw another note about using the internal global LDO.  We would like to prioritize performance over power, and was wondering if TI suggests using the internal LDO or not.
  2. If we plan to boot from internal flash, there are no GPIO requirements for boot right?
  3. We plan to release this product in China, and use the 779MHz ISM band.  We plan to use the Johanson 0850BM14E0016 balun.  I came across this forum post regarding the radio config of the CC1312 at 779MHz, and wanted to check if this was finalized or not
