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).
124
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 and clock/buzzer output.
Reset signal generation sets port 14 to input mode.
Figure 4-27 shows block diagrams of port 14.
Caution
To use P140/PCLBUZ0/INTP6 or P141/PCLBUZ1/INTP7 as a general-purpose port, set bit 7 of
clock output select register 0 and 1 (CKS0, CKS1) to “0”, which is the same as their default
status setting.
