Port 9 is an I/O port with an output latch. Port 9 can be set to the input mode or output mode in 1-bit units using port
mode register 9 (PM9). When the P90 to P97 pins are used as an input port, use of an on-chip pull-up resistor can be
specified in 1-bit units by pull-up resistor option register 9 (PU9).
This port can also be used for segment output.
Reset signal generation sets port 9 to input mode.
Figures 4-25 and 4-26 show block diagrams of port 9.
