Could you explain BCC command to me?

Hi,

I find C code not executing in the desired way. Then I step in assembly code of Tiva-C M4F core. Below is the disassembly code:

$C$L5:   nop

0000033a:   280A     CMP             R0, #10

0000033c:   D3C9     BCC             $C$L5

here_label:

R0 is '0'. It is found that after BCC exec, the core  goes $C$L5, not goes to here_label.

In xPSR, 'C' is '0'. I want to know BCC in detail, but the found description online is ambiguous to me. Especially the last column comments on Arithmetic. Could you explain the disassembly code running when flag 'C'=0, it goes to $C$L5, not here_label?

Thanks,
