MPC555 branch instruction

Hello list,
Has anyone seen a compiler generate an instruction for the MPC555 that looks
like this:
0x41A20000
BC 0x0D, 0x02, 0 This is what my debugger says it is.
Beq+ 14 <outbyte+0x14> This is what is in the disassembled object
file.
I can't find this instruction in the programming environment manual so can't
figure out how it is suppose to work. It is branching to itself and hanging
my code. It is suppose to be polling a bit in the SCI interface to check and
see if the transmitter is free to transmit another byte, but it never moves
on from there.
Any help you might be able to offer would be appreciated.
Thanks,
Dave
