4.2.11 Port 14
using port mode register 14 (PM14). When the P140 and P141 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 14 (PU14).

Port 14 is a 2-bit I/O port with an output latch. Port 14 can be set to the input mode or output mode in 1-bit units
This port can also be used for external interrupt request input, buzzer output, and clock output.
RESET input sets port 14 to input mode.
Figure 4-20 shows a block diagram of port 14.
