4.3 Function

TMP89FS60

RA000

4.3.2

External interrupt 0

External interrupt 0 detects the falling edge of the INT0 pin and generates interrupt request signals.

In NORMAL1/2 or IDLE1/2 mode, pulses of less than 1/fcgck are removed as noise and pulses of 2/fcgck or

more are recognized as signals.

In SLOW/SLEEP mode, pulses of less than 4/fs are removed as noise and pulses of 8/fs or more are recog-

nized as signals.

4.3.3

External interrupts 1/2/3

External interrupts 1/2/3 detect the falling edge, the rising edge or both edges of the INT1, INT2 and INT3

pins and generate interrupt request signals.

4.3.3.1

Interrupt request signal generating condition detection function

Select interrupt request signal generating conditions at EINTCRx<INTxES> for external interrupts 1/2/

Note: x=1 to 3

4.3.3.2

A noise canceller pass signal monitoring function when interrupt request signals are

generated

The level of a signal that has passed through the noise canceller when an interrupt request is generated

can be read by using EINTCRx<INTxLVL>. When both edges are selected as detection edges, the edge

where an interrupt is generated can be detected by reading EINTCRx<INTxLVL>.
