Figure 17.10 shows the PACR register. After reset, set bits PACR2 to PACR0 in the PACR register before
a signal is input or output to each pin. When bits PACR2 to PACR0 are not set, some pins do not function
as I/O ports.
Bits PACR2 to PACR0: control pins to be used
U1MAP bit: controls pin assignments for the UART1 function.

The PRC2 bit in the PRCR protects the PACR register. Set the PACR register after setting the PRC2 bit in
the PRCR register.
Two digital debounce function circuits are provided. Level is determined when level is held, after applying
either a falling edge or rising edge to the pin, longer than the programmed filter width time. This enables
noise reduction.
This function is assigned to INT5/INPC17 and NMI/SD. Digital filter width is set in the NDDR register and
the P17DDR register respectively. Figure 17.11 shows the NDDR register and the P17DDR register.
Additionally, a digital debounce function is disabled to the port P1
Filter width : (n+1) x 1/f8
The NDDR register and the P17DDR register decrement count value with f8 as the count source. The
NDDR register and the P17DDR register indicate count time. Count value is reloaded if a falling edge or a
rising edge is applied to the pin.
The NDDR register and the P17DDR register can be set 00
