and then write the results back to the latches or the ac-
cumulator.
Each line of port A has the capability of waking-up the
device. The pull-high resistor of each I/O line is decided
by options.
Comparator
There is a comparator implemented in this
microcontroller. This comparator can be enabled/dis-
abled by options. Its inputs are CMPP(+) and CMPN(-)
and outputs are CMPO and CHGO. When the CMPN in-
put level is less than the level of CMPP, the CMPO out-
putisV
DD
.WhentheCMPNinputlevelishigherthanthe
level of CMPP, the CMPO output is V
SS
.
The CHGO signal is combined with CMPO and
32768Hz carrier if 32768Hz RTC oscillator is applied.
This comparator also can be disabled by options. When
the system enters halt mode, the comparator is disabled
to reduce power consumption. Once the comparator is
disabled, the CHGO and CMPO will stay at VSS level.
LCD Display Memory
The micro-controller provides an area of embedded
data memory for LCD driver. This area is located from
40H to 53H of he RAM Bank 1. Bank pointer (BP; lo-
cated at 04H of the RAM) is the switch between the gen-
eral purpose RAM and the LCD display memory. When
the BP is set to
1
, any data written into 40H~53H (indi-
rect accessing by using the MP1and R1) will effect the
LCD display. When the BP is cleared to
0
, any data
written into 40H to 53H will access the general purpose
data memory. The LCD display memory can be read
and written to only by indirect addressing mode using
MP1. When data is written into the display data area it is
automatically read by the LCD driver which then gener-
ates the corresponding LCD driving signals. To turn the
display on or off, an
1
or a
0
is written to the corre-
sponding bit of the display memory, respectively. The
figure illustrates the mapping between the display mem-
ory and LCD pattern for the micro-controller.
LCD Driver Output and Bias Circuit
The output number of the micro-controller LCD driver
can be 2
0 3 or 19 4
by options (ie., 1/3 duty or 1/4
duty). The bias type of LCD driver is
R
type, no exter-
nal capacitor is required. The LCD can be optioned as
LCD on at HALT
or
LCD off at HALT which are de-
pendent on options.
The SEG7~SEG18 also can be optioned as logical out-
puts. Each group of
SEG7~SEG10, SEG11~SEG14
and SEG15~SEG18 can be optioned individually. Once

tents of bit 0 of the related segment address in LCD
RAM will appear on the segment.
