8.9
Port 8 is an 8-bit I/O port. Port 8 pins also function as SCI_1 I/O pins, the IIC_1 I/O pin, XBS I/O
pins, LPC I/O pins, and interrupt input pins. The output type of P86 and SCK1 is NMOS push-pull
output. The output type of SCL1 is NMOS open drain output and direct bus driving is enabled.
Port 8 pin functions are the same in all operating modes except host interface function. Port 8 has
the following registers.
8.9.1
P8DDR specifies input or output for the pins of port 8 on a bit-by-bit basis.

The initial value must not be changed.
P8DDR has the same address as PBPIN, and if
read, the port B state will be returned.
The corresponding port 8 pins are output ports
when P8DDR bits are set to 1, and input ports
when cleared to 0.
