6.2.11 Port 9
mode register 9 (PM9). When the P90 and P91 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).

P90
P91
P91 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
Reset signal generation sets port 9 to input mode.
Figure 6-39 shows a block diagram of port 9.
