FUNCTION TABLE OF IC

Input/
Output
Input/Output Used to input or output 4 bits at a time. When the output latch is set to "1", the unit will be in the
input mode. The key-on wakeup function, which can be switched on or off by the software, and a
pull-up transistor, which can be turned on or off by the software, are built in.
Input/Output Used to input or output 4 bits at a time. When the output latch is set to "1", the unit will be in the
input CK (VOL), mode.The key-on wakeup function, which can be switched on or off by the software,
and a pull-up transistor,which can be turned on or off by the software, are built in.
Input/Output Each terminal can be used to input or output 1 bit at a time. The output section has a latch which
holds 1 bit. One of the D ports is assigned by register Y as a data point, to execute input or output.
To use the port for input, set the output latch for that bit to "1". All of the output latches on port D can
be set to "1" using the CLD command.

Input/Output Used to receive 4 bits at a time.
Input/Output Reset pulse input/output terminal. When a reset is caused by the watch dog timer, an "L" level will
be output. The output is an N channel open drain.
Input Input/output terminals for the main clock generation circuit. Used by connecting a ceramic resonator
between the XIN and XOUT terminals. There is a built-in feedback resistor between the XIN and
XOUT terminals.

— Positive power supply terminal.
Output Input/output terminals for the sub clock generation circuit. Used by connecting a crystal oscillator
between the XCIN and XCOUT terminals. There is a built-in feedback resistor between the XCIN
and XCOUT terminals.

Input LCD power input terminals. To use the internal resistor, connect VLC3 to VDD (if a brightness
control is needed, connect VLC3 to VDD through a resistor). When an external power supply is
used, applyvoltages as follows: 0<VLC1<VLC3<VLCD<VDD.
Output LCD common output terminals.
Output LCD segment output terminals.
