After the UBC register is updated, execute one of the following three methods.
A. Read the updated UBC register, and execute a branch using the RTE instruction.
B. Execute the ICBI instruction for any address (including non-cacheable area).
C. Set 0 (initial value) to IRMCR.R1 before updating the UBC register and update with
specified as the match condition.
conditions for the first and second channels in the sequence are satisfied in this order.
Therefore, if the conditions are set so that the conditions for channels 0 and 1 should be
satisfied simultaneously for the same bus cycle, the sequential break conditions will not be
satisfied, causing no break.
instruction fetch cycle is the match condition. For the instructions preceding the SLEEP
instruction by one to five instructions, do not allow the break where the operand access is the
match condition.
according to the specified priority. For the priority, refer to section 5, Exception Handling. If
the exception having the higher priority occurs, the user break does not occur.
⎯ The pre-instruction-execution break is accepted prior to any other exception.

register.)

a. Write the UBC register.
b. Read the UBC register which is updated at 1.
c. Write the value which is read at 2 to the UBC register.

these methods.
