14.4 Noise Eliminator

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.

P01/ESO0/INTP0, P02/ESO1/INTP1

P03/ADTRG0/INTP2,

P04/ADTRG1/INTP3

P05/INTP4 to P07/INTP6

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.
