4.2.11 Port 14
mode register 14 (PM14). When the P141 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).
P140/PCLBUZ0
P141/PCLBUZ1
P140 is a output port with an output latch.
P141 is I/O port with an output latch. P141 can be set to the input mode or output mode in 1-bit units using port
This port can also be used for clock/buzzer output.
Reset signal generation sets P141 to input mode.
Figures 4-26 and 4-27 show block diagrams of port 14.
Caution To use P140/PCLBUZ0 and P141/PCLBUZ1 as general-purpose ports, set bit 7 of clock output
select registers 0 and 1 (CKS0, CKS1) to “0”, which is the same as their default status setting.
