All instructions execute in a single cycle.
Extensive set of interrupt functions for clearing halt and
hold mode
— 8 halt mode clearing functions
— 5 hold mode clearing functions
— 6 interrupt functions
— Subroutines can be nested up to 8 levels (Special-
purpose registers that are shared with the interrupt
function are built in.)
Powerful hardware to increase system processing capacity
— Segment port related hardware
Built-in segment PLA circuit
Built-in segment decoder
Support for six different LCD drive specifications
Outputs can be switched to CMOS levels
— Built-in 8-bit synchronous serial I/O circuit
— 8-bit read/write timer (plus a separate 8-bit
prescaler; can be used as and event counter)
— 8-bit reload timer (plus built-in 8-bit prescaler)
— Built-in 8-bit prescaler (for use with timer 1, timer 2,
and the serial counter)
— All of RAM can be used a working area (RAM bank
system)
— Dedicated data pointer register for RAM access
— 15-stage divider circuit for clocks (also used as the
LCD voltage alternation frequency generator)
— 8-bit table reference function (reads 8-bit ROM data)
— Chattering prevention circuit (on two ports)
— Alarm signal generation circuit
LCD panel drive output pins with high flexibility
(42 pins)
— The LCD output pins can be switched to function as
general-purpose outputs.
CMOS/p-channel/n-channel type combinations: Up
to 42 pins
— An alternation frequency appropriate for the LCD
panel used can be selected.
An oscillator appropriate for your system’s specifications
can be selected.
— A 32- or 65-kHz crystal oscillator can be selected
(Used when a clock function is required or for low
current drain operation.)
— A ceramic oscillator with a frequency from 400 kHz
to 2 MHz can be selected (when high-speed
operation is required.)
