instruction, which has higher priority is determined according to the priority levels defined in
table 5.1 in section 5, Exception Handling. If an exception source with higher priority occurs,

placed. If the address of the lower 16 bits is set and a break before instruction execution is set
as a break condition, the break is handled as a break after instruction execution.
after instruction execution is set for the DIVU or DIVS instruction and an exception or
interrupt occurs during execution of the DIVU or DIVS instruction, a break after instruction
execution occurs even though execution of the DIVU or DIVS instruction is halted.
instruction. If a pre-execution break is set for the instruction that comes after the DIVU or
DIVS instruction and an exception or interrupt occurs during execution of the DIVU or DIVS
instruction, a pre-execution break occurs even though execution of the DIVU or DIVS
instruction is halted.
address. For example, if a pre-execution break for channel 0 and a break after instruction
execution for channel 1 are set simultaneously for one address, a break generated prior to
instruction execution for channel 0 can set a condition-match flag after the instruction
execution for channel 1.
