UG470 v1.13.1 (which appears to be the most current one) appears to be missing a few steps in Table 10-4 "Single Device Configuration Sequence."
Step 8 says to stay in the RTI state for 10 ms (10K clocks @ 1 MHz), but then Step 9 strangely just says "Start loading the CFG_IN instruction, LSB first," specifying TMS as 0, TDI as 00101, and 5 clocks.
This seems to be missing actually *going* to SHIFT_IR, which would require doing steps 3 and 4 again (move to Select-IR, TMS=1, 2 clocks, and move to Shift-IR, TMS=0, 2 clocks).
Am I missing something or is the documentation wrong here?

Yes to make any command work you should first enter into SHIFT-IR.
RTI just a padding time state.
