FUNCTION TABLE OF IC

Port Name Input/
Output
MTCONT2 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.
POWER-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
DATA (VOL), transistor,which can be turned on or off by the software, are built in.
STB (VOL)
POWER-ON 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.
MUTE 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.
SYNC-OUT, Input/Output Each terminal can be used to input or output 1 bit at a time. The output section has a latch which holds
RES,CQCK, 1 bit. One of the D ports is assigned by register Y as a data point, to execute input or output.
COIN,REC 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.
SL+,SL- 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.
SRS2,SRS1 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.
DRF Input/Output Used to receive 4 bits at a time.
SQOUT Input/Output Used to receive 4 bits at a time.
WRQ Input/Output Used to receive 4 bits at a time.
PU-IN 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.
Output 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.
— GND input terminal.
— 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 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 GND input terminal for the A-D converter.
Input Reference voltage input terminal for the A-D converter.
REMOCONINT2 Input Used to receive 4 bits at a time.
TORAY1 Input Used to receive 4 bits at a time.
TORAY2 Input Used to receive 4 bits at a time.
Input Used to receive 4 bits at a time.
Input Used to receive 4 bits at a time.
Input Used to receive 4 bits at a time.
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, apply
voltages as follows: 0<VLC1<VLC3<VLCD<VDD.
Output LCD common output terminals.
Output LCD segment output terminals.
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.
