Port 14 is an I/O port with an output latch. Port 14 can be set to the input mode or output mode in 1-bit units using port
mode register 14 (PM14). When the P140 to P147 pin is 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 14 (PU14).
This port can also be used for segment output.
Reset signal generation sets Port 14 to input mode.
Figures 4-33 and 4-34 show block diagrams of port 14.
