I
—
Selects interface mode with the MPU;
Low: Serial mode
High: 4-bit/8-bit bus mode
(Bus width is specified by instruction.)
RS/CS*
1
I
MPU
Selects registers during bus mode:
Low: Instruction register (write);
Busy flag, address counter (read)
High: Data register (write/read)
Acts as chip-select during serial mode:
Low: Select (access enable)
High: Not selected (access disable)
RW/SID
1
I
MPU
Selects read/write during bus mode;
Low: Write
High: Read
Inputs serial data during serial mode.
E/SCLK
1
I
MPU
Starts data read/write during bus mode;
Inputs (Receives) serial clock during serial mode.
DB4 to
DB7
4
I/O
MPU
Four high-order bidirectional tristate data bus pins.
Used for data transfer between the MPU and the
HD66712. DB7 can be used as a busy flag. Open
these pins during serial mode since those signals.
DB1 to
DB3
3
I/O
MPU
Three low order bidirectional tristate data bus pins.
Used for data transfer between the MPU and the
HD66712. Open these pins during 4-bit operation or
serial mode since they are not used.
DB0/ SOD
1
I/O
/O
MPU
The lowest bidirectional data bit (DB0) during 8-bit bus
mode. Open these pins during 4-bit mode since they
are not used.
Outputs (transfers) serial data during serial mode.
Open this pin if reading (transfer) is not performed.
COM0 to
COM33
34
O
LCD
Common signals; those that are not used become non-
selected waveforms. At 1/17 duty rate, COM1 to
COM16 are used for character display, COM0 and
COM17 for icon display, and COM18 to COM33
become non-selected waveforms. At 1/33 duty rate,
COM1 to COM32 are used for character display, and
COM0 and COM33 for icon display. Because two COM
signals output the same level simultaneously, apply
them according to the wiring pattern of the display
device.
SEG1 to
SEG60
60
O
LCD
Segment output signals
