tomatically after the measurement cycle is completed.
But in the other two modes the TON can only be reset by
instructions. The overflow of the timer/event counter is
one of the wake-up sources. No matter what the opera-
tion mode is, writing a 0 to ET can disable the corre-
sponding interrupt services.
In the case of timer/event counter OFF condition, writing
data to the timer/event counter preload register will also
reload that data to the timer/event counter. But if the
timer/event counter is turned on, data written to it will
only be kept in the timer/event counter preload register.
The timer/event counter will still operate until overflow
occurs (a timer/event counter reloading will occur at the
same time). When the timer/event counter (reading
TMR) is read, the clock will be blocked to avoid errors.
As clock blocking may result in a counting error, this
must be taken into consideration by the programmer.
Input/Output Ports
There are 12 bidirectional input/output lines in the
microcontroller, labeled from PA to PB, which are
mapped to the data memory of [12H] and [14H] respec-
tively. All of these I/O ports can be used for input and
output operations. For input operation, these ports are
non-latching, that is, the inputs must be ready at the T2
rising edge of instruction MOV A,[m] (m=12H or 14H).
For output operation, all the data is latched and remains
unchanged until the output latch is rewritten.
EachI/Olinehasitsowncontrolregister(PACandPBC)
to control the input/output configuration. With this con-
trol register, CMOS/NMOS/PMOS output or Schmitt
trigger input with or without pull-high/low resistor struc-
tures can be reconfigured dynamically under software
control. To function as an input, the corresponding latch
of the control register must write a 1 . The input source
also depends on the control register. If the control regis-
ter bit is 1 , the input will read the pad state. If the con-
trol register bit is 0 , the contents of the latches will
move to the internal bus. The latter is possible in the
read-modify-write
CMOS/NMOS/PMOS configurations can be selected
(NMOS and PMOS are available for PA only). These

instruction. For output function,
Afterachipreset,theseinput/outputlinesremainathigh
levels or in a floating state (depending on the
pull-high/low options). Each bit of these input/output
latches can be set or cleared by SET [m].i and CLR
[m].i (m=12H or 14H) instructions.
Some instructions first input data and then follow 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 accumulator.
Each line of port A has the capability of waking-up the
device.
There are pull-high/low (PA only) options available for
I/O lines. Once the pull-high/low option of an I/O line is
selected, the I/O line have pull-high/low resistor. Other-
wise, the pull-high/low resistor is absent. It should be
noted that a non-pull-high/low I/O line operating in input
mode will cause a floating state.
It is recommended that unused or not bonded out I/O

to avoid consuming power under input floating state.
