Hello,
Register FSFR1 was deleted from the TRM at SPNU499B. I suspect it was due to the issue discussed in this thread:
http://e2e.ti.com/support/microcontrollers/hercules/f/312/t/220536.aspx
sys_selftest.c still uses this register in HALCoGen. The usage seems benign per the action described in the thread as long as the function of FSRF1 is not changed on a future silicon revision. Will the document or HALCoGen be updated?
Thanks, Charlie Johnston
