14.4 Noise Eliminator
14.4.1 Interrupt pins
A timing controller to guarantee the noise elimination times shown below is added to the pins that operate as NMI
and valid edge inputs in port control mode. Signal input that changes in less than these elimination times is not
accepted internally.
Pin
Noise Elimination Time
P00/NMI
P01/ESO0/INTP0, P02/ESO1/INTP1
P03/ADTRG0/INTP2,
P04/ADTRG1/INTP3
P05/INTP4 to P07/INTP6
Analog delay (Approx. 10 ns)
Cautions 1. The above non-maskable/maskable interrupt pins are
used to release standby mode. A clock control timing
circuit is not used since the internal system clock is
stopped in standby mode.
2. The noise eliminator is valid only in control mode.
