identified according to the settings of the I flag in the condition code register (CCR), the interrupt
level mask register (ILM), and the interrupt control register (ICR). In the sub-watch mode, no

Note:
When interrupt processing is executed, the CPU normally executes the instruction following the
instruction in which the watch mode has been specified. The CPU then proceeds to interrupt processing.
