What Johnny said. The prompt says "(O)", not "(0)" - the letter O for
Octal. The zero after that isn't a default, it simply means that the
value hasn't been set.
There is no default. Or at least no sane one. Zero in this case means
that it's writing to memory address zero for CSR. The diagnostic should
reject that, but diagnostics are notoriously user unfriendly.
