Pin Function
Note: * The program development tool (emulator) does not support this function. (n = 5 to 0)
7.9
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, 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 has the
following registers.
7.9.1
P8DDR specifies input or output for the pins of port 8 on a bit-by-bit basis.

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.
