20.4 External Interrupt Request Input Pins (INTP00 to INTP18, INTADT0, INTADT1)
20.4.1 Noise elimination
20.4.2 Edge detection
V850E/IG3: n = P00 to P18, ADT0, ADT1). The edge that can be selected as the valid edge is one of the following.
1010
(1) Noise elimination of INTP00, INTP01, INTPa (V850E/IG3 only), INTP08 to INTP13, INTP17, INTP18,
(2) Noise elimination of INTP14 to INTP16 pins
The valid edges of the INTn pin can be selected by program (V850E/IF3: n = P00, P01, P08 to P18, ADT0, ADT1,
• Rising edge
• Falling edge
• Both the rising and falling edges
The edge-detected INTn signal becomes an interrupt source.
The valid edge is specified by the INTR0 to INTR2, ADTR, INTF0 to INTF2, and ADTF registers.
INTADT0, and INTADT1 pins
The INTP00, INTP01, INTPa (V850E/IG3 only), INTP08 to INTP13, INTP17, INTP18, INTADT0, and INTADT1
pins incorporate a noise eliminator that uses analog filter (a = 02 to 07). Unless, therefore, the input level of
each pin is held for a certain time, an edge cannot be detected. An edge is detected after a certain time has
elapsed.
The INTP14 to INTP16 pins incorporate a digital noise eliminator.
The sampling clock that performs digital sampling can be selected by the INTNFCm.INTNFCm2 to
INTNFCm.INTNFCm0 bits (m = 14 to 16).
The system clock stops in the IDLE and STOP modes, so the INTP14 to INTP16 pins cannot be used to cancel
the IDLE and STOP modes.
