High level interrupt

Note 1:

The INT0 pin can also be used for standby release as described later. Even if the pin is not used for standby

release, setting this register to “0” maintains the port function during standby mode.

Note 2:

Case of changing from level to edge for INT0 pin mode (<I0LE> “1”

→ “0”)

Execution example:

(INTE0AD), XXXX0000B

;

INT0 disable, clean the request flag.

(IIMC), XXXXX10XB

;

Change from level to edge.

(INTE0AD), XXXX0nnnB

;

Set interrupt level “n” for INT0, clear the request flag.

Note 3:

IIMC<bit7:3> is always read as “1”.

Note 4:

See electrical characteristics in section 4 for external 4 for external interrupt input pulse.
