This is the command list extracted fro m the source code:
T = dump exception log buffer.
b`reak-'s`et' <addr> = set breakpoint.
b`reak-'d`elete at' <addr> = delete breakpoint.
b`reak-'p`rint' = list breakpoints.
r = print registers.
I <addr> = List instaructions at addr.
c = continue execution.
S = stack backtrace.
s = step over 'jal'. (sets temp bp at current addr+8).
= single step.
i`n'-[bhw] <addr> = read byte,hword, word from address.
o`ut'-[bhw] <addr>,<value> output byte, hword, word to address.
t = dump translation buffer.
f`lush-'t`lb' = flush translation buffer.
f`lush-'c`ache' = flush cache.
Note though that from 2.3 arc kernels uses ddb.
