[m].i" and "CLR [m].i" (m=12H, 14H or 16H) in-
structions.
Some instructions first input data and then fol-
low the output operations. For example, "SET
[m].i", "CLR [m].i", "CPL [m]", "CPLA[m]" read
the entire port states into the CPU, execute the
defined operations (bit-operation), and then
write the results back to the latches or the accu-
mulator.
Each line of port A has the capability of wak-
ing-up the device. The highest 3-bit of port C are
not physically implemented; on reading them a
"0" is returned whereas writing then results in a
no-operation. See Application note.
There is a pull-high option available for all I/O
ports (byte option). Once the pull-high option of
an I/O port is selected, all I/O lines have
pull-high resistors. Otherwise, the pull-high re-
sistors are absent. It should be noted that a
non-pull-high I/O line operating in input mode
will cause a floating state.
The PB0 and PB1 are pin-shared with BZ and
BZ signal, respectively. If the BZ/BZ option is
selected, the output signal in output mode of
PB0/PB1 will be the PFD signal generated by
timer/event counter overflow signal. The input
mode always remaining its original functions.
Once the BZ/BZ option is selected, the buzzer
output signals are controlled by PB0 data regis-
ter only. The I/O functions of PB0/PB1 are
shown below.

The PC0 and PC1 are pin-shared with INT,
TMR and pins respectively.
In case of Internal RC+I/O system oscillator,
the PC3 and PC4 are pin-shared with OSC1
and OSC2 pins. Once the Internal RC+I/O
mode is selected, the PC3 and PC4 can be used
as general purpose I/O lines. Otherwise, the
pull-highresistorsandI/OfunctionsofPC3and
PC4 will be disabled.
It is recommended that unused or not bonded
out I/O lines should be set as output pins by
software instruction to avoid consuming power
under input floating state.
