Figure 16.4.1 shows the port control register.
When the P1 register is read after setting the PCR0 bit in the PCR register to “1”, the corresponding port
latch can be read no matter how the PD1 register is set.
Figure 16.5.1 shows the PACR. After reset set the PACR2 to PACR0 bit before you input and output it to
each pin. When the PACR register isn’t set up, the input and output function of some of the pins doesn’t
work.
PACR2 to PACR0 bits: control the pins enabled for use.
U1MAP: controls the assignment of UART1 pins.
PACR is write protected by PRC2 bit in the PRCR register. PRC2 bit must be set immediately before the
write to PACR.
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. Additionally, a digital debounce function is disabled to the port P1
input and port P8
Filter width :
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
