Ports
Input-only pins
Port S (4 pins)
The INT pin (1 pin)
I/O Pins
Port K (4 pins)
The output circuits are CMOS circuits, and cannot be modified.
Port M (4 pins)
The output circuits are either CMOS or p-channel circuits, and the type can be selected under program control in single-port units.
(The M4 pin is set to its input pin function when timer 2 is used as an event counter.)
Port SO (4 pins)
The output circuits are either CMOS or n-channel circuits, and the type can be selected under program control in single-port units.
The three pins SO1, SO2, and SO3 also function as the serial interface pins. (Two-pin serial interface operation is also supported.)
Port P (4 pins)
The output circuits are either CMOS or p-channel circuits, and the type can be selected under program control in single-port units.
Output-only pins
Port N (4 pins)
The N3 pin also functions as the remote controller carrier output pin, and the N4 pin also functions as the alarm output pin.
LCD drive pins
Common pins (4 pins)
Segment pins (23 pins)
The segment pin circuits include built-in memory (called “segment memory”) that holds the output data. These pins can also
be switched in single-pin units in the mask options to function as general-purpose outputs (CMOS, p-channel, or n-channel).
Wide selection of LCD drive techniques
LCD controller (Hardware functions that facilitate the development of display control software)
Segment PLA (option)
This technique allows the LCD drivers (common 1 through common 4) to be controlled according to user software
design, i.e. the relationship between LCD segment control strobe signals and the data. This technique is more difficult
for the chip manufacturer, but it allows software design and the LCD panel layout design to be completely independent.
Thus it supports highly efficient product development and is a major plus for the user. Furthermore, there is no need for
a routine that converts data held in RAM to LCD driver output data.
Segment decoder
These microcontrollers provide a decoder for 7-segment displays. This circuit also allows binary data to be output
without modification for display control of flag areas that display various operating states.
Strobe decoder
This function groups segments for easier program development and display control.
