8.9
Port 9 is an 8-bit I/O port. Port 9 pins also function as the bus control I/O pins or the system clock
output pin. Pin functions are switched depending on the operating mode. Port 9 has the following
registers.
• Port 9 data direction register (P9DDR)
• Port 9 data register (P9DR)
8.9.1
The individual bits of P9DDR specify input or output for the pins of port 9.

Description
If port 9 pins are specified for use as the general I/O
port, the corresponding port 9 pins are output ports
when the P9DDR bits are set to 1, and input ports
when cleared to 0.
When this bit is set to 1, the corresponding port 96 pin
is the system clock output pin (φ), and as a general
input port when cleared to 0.
If port 9 pins are specified for use as the general I/O
port, the corresponding port 9 pins are output ports
when the P9DDR bits are set to 1, and input ports
when cleared to 0.
