(7) Noise elimination control register (INTNFC)
Remarks 1. Since sampling is performed 3 times, the reliably eliminated noise width is 2 sampling clocks.
Analog noise elimination and digital noise elimination can be selected for the INTP02 pin. The noise elimination
settings are performed using the INTNFC register.
When analog noise elimination is selected, the input level of the pin is detected as an edge by maintaining it for a
specific time or longer.
When digital noise elimination is selected, the sampling clock for digital sampling can be selected from among

Even when digital noise elimination is selected, using f
interrupt request signal to release the IDLE1, IDLE2, and STOP modes.
This register can be read or written in 8-bit units.
Reset sets this register to 00H.

the sampling clock has been changed, an interrupt request signal may be generated. Therefore,
be careful about the following points when using the interrupt and DMA functions.
