Section 8 I/O Ports
Note:
8.6
Port 5 is a 3-bit I/O port. Port 5 pins also function as SCI_0 I/O pins, and the IIC_0 I/O pin. P52
and SCK0 are NMOS push-pull outputs, and SCL0 is an NMOS open-drain output. Port 5 has the
following registers.
8.6.1
P5DDR specifies input or output for the pins of port 5 on a bit-by-bit basis.

Description
Reserved
The initial value must not be changed.
The corresponding port 5 pins are output ports
when P5DDR bits are set to 1, and input ports
when cleared to 0. As SCI_0 is initialized in
software standby mode, the pin states are
determined by the IIC_0 ICCR, P5DDR, and
P5DR specifications.
