16.4.4  Putting interrupt requests on hold 
If an interrupt request (such as a maskable, non-maskable, or external interrupt) is generated when a certain type 
of instruction is being executed, the interrupt request will not be acknowledged until the instruction is completed.  Such 
instructions (interrupt request pending instructions) are as follows. 
 
•  Instructions that manipulate interrupt request flag registers (IF0 to IF2) 
•  Instructions that manipulate interrupt mask flag registers (MK0 to MK2)
