period from executing an instruction to rewrite the UBC register till the new value is actually
rewritten, the desired break may not occur. In order to know the timing when the UBC register
is changed, read from the last written register. Instructions after then are valid for the newly
written register value.
A condition match occurs when a B-channel match occurs in a bus cycle after an A-channel
match occurs in another bus cycle in sequential break setting. Therefore, no break occurs even
if a bus cycle, in which an A-channel match and a channel B match occur simultaneously, is
set.
priority is determined according to the priority levels defined in table 4.1 in section 4,
Exception Handling. If an exception with higher priority occurs, the user break is not
generated.
Pre-execution break has the highest priority.
When a post-execution break or data access break occurs simultaneously with a re-
When a post-execution break or data access break occurs simultaneously with a
If a post-execution break or data access break is satisfied by an instruction that generates a
CPU address error (or TLB related exception) by data access, the CPU address error (or TLB
related exception) is given priority to the break. Note that the UBC condition match flag is set
in this case.
execution-type exception (including pre-execution break) that has higher priority, the re-
execution-type exception is accepted, and the condition match flag is not set (see the
exception in the following note). The break will occur and the condition match flag will be
set only after the exception source of the re-execution-type exception has been cleared by
the exception handling routine and re-execution of the same instruction has ended.
completion-type exception (TRAPA) that has higher priority, though a break does not
occur, the condition match flag is set.
