Preliminary
put/outputlatchescanbesetorclearedby"SET
[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 6-bit of port C and
5 bits of port B are not physically implemented;
on reading them a "0" is returned whereas writ-
ing then results in a no-operation. See Applica-
tion note.
There is a pull-high option available for all I/O
lines. Once the pull-high option is selected, all
I/O lines have pull-high resistors. Otherwise,
the pull-high resistors 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 as
shown below.
