Note When not using the external interrupt function, the INT pin can be used as an input-only pin (sense input).

As a sense input, the pin status is read not by the port register but by the control register's INT flag.

Caution Despite a high level of functional compatibility with the masked ROM product, the PROM product

is different in terms of the internal ROM circuit and some electric features. When switching from

a PROM to a masked ROM product, be sure to sufficiently evaluate the application of the masked

ROM product based on its sample.
