Figure 17-11 shows the timing at which interrupt requests are held pending.
Caution The BRK instruction is not one of the above-listed interrupt request hold instructions. However,

registers.
××IF
the software interrupt activated by executing the BRK instruction causes the IE flag to be
cleared. Therefore, even if a maskable interrupt request is generated during execution of the
BRK instruction, the interrupt request is not acknowledged.
2. Instruction M: Instruction other than interrupt request hold instruction
3. The ××PR (priority level) values do not affect the operation of ××IF (interrupt request).
