7.10
Port 9 is an 8-bit I/O port. Port 9 pins also function as the interrupt input pins, IIC_0 I/O pin,
subclock input pin, and system clock ( ) output pin. P97 is an NMOS push-pull output. SDA0 is
an NMOS open-drain output, and has direct bus drive capability. Port 9 has the following
registers.

Description
When the corresponding P9DDR bits are set to 1, pin P96
functions as the
become output ports. When P9DDR bits are cleared to 0,
the corresponding pins become input ports.
