Pin Connect

Hello. I write assembler for TMS320C54x. I have next instruction:

bc start, nbio,

which mean when pin BIO=1, then PC=START, else PC=PC+2. I use tool Pin Connect in CodeComposer for setting value of pin BIO:

[1,0] ([+1,0])rpt EOS.

I clear BIO, but simulator of CodeComposer execute bc start, nbio as if BIO=1. What am I doing wrong?
