3. Interrupt Control Circuit
3.8 External Interrupts
TMP86FH09ANG
Note 1: In NORMAL1/2 or IDLE1/2 mode, if a signal with no noise is input on an external interrupt pin, it takes a maximum of "sig-
nal establishment time + 6/fs[s]" from the input signal's edge to set the interrupt latch.
Note 2: When INT0EN = "0", IL4 is not set even if a falling edge is detected on the INT0 pin input.
Note 3: When a pin with more than one function is used as an output and a change occurs in data or input/output status, an inter-
rupt request signal is generated in a pseudo manner. In this case, it is necessary to perform appropriate processing such
as disabling the interrupt enable flag.

Pulses of less than 2/fc [s] are eliminated as
noise. Pulses of 7/fc [s] or more are considered
to be signals. In the SLOW or the SLEEP mode,
pulses of less than 1/fs [s] are eliminated as
noise. Pulses of 3.5/fs [s] or more are consid-
ered to be signals.

Pulses of less than 15/fc or 63/fc [s] are elimi-
nated as noise. Pulses of 49/fc or 193/fc [s] or
more are considered to be signals. In the SLOW
or the SLEEP mode, pulses of less than 1/fs [s]
are eliminated as noise. Pulses of 3.5/fs [s] or
more are considered to be signals.
