External Interrupts

There are 5 external interrupts in this LSI. The circuit (external interrupt interface) for the external interrupt input

signal, is built-in between the external interrupt input pin and the interrupt controller block. This external inter-

rupt interface can manage to do with any kind of external interrupts.

Table 3-3-1 shows the list 

of

 functions which external interrupts 0 to 4 can be used.
