An 8-bit bidirectional data bus is used to connect an 8-bit or 16-bit
standard MPU data bus.
When the serial interface is selected (P/S=LOW),
In this case, D0 to D5 are set to high impedance.
When Chip Select is in the non-active state, D0 to D7 are set to
high impedance.
Normally the lowest order bit of the MPU address bus is connected
to discriminate data / commands.
Initialized by setting RES to LOW.
Reset operation is performed at the RES signal level.
Chip Select signal. When CS1=LOW and CS2=HIGH, this signal
becomes active and the input/output of data/commands is enabled.
• When the 80 series MPU is connected, active LOW is set.
• When the 68 series MPU is connected, active HIGH is set.
• When the 80 series MPU is connected, active LOW is set.
• When the 68 series MPU is connected,
Output pin for static drive
Used together with the SYNC pin
MPU interface switching pin
Switching pin for parallel data entry/serial data entry
P/S=HIGH: Parallel data entry
P/S=LOW: Serial data entry
According to the P/S state, the following table is given.
When P/S=LOW, D0 to D5 are set to high impedance. D0 to D5 can
be HIGH, LOW, or “OPEN”.
RD(E) and WR (R/W) are fixed to HIGH or LOW.
For the serial data entry, RAM display data cannot be read.
Pin that connects the RD signal of the 80 series MPU. When this
signal is LOW, the S1D15705 series data bus is set in the output state.
68 series MPU enable clock input pin
Pin that connects the WR signal of the 80 series MPU. The data
bus signal is latched on the leading edge of the WR signal.
Read/write control signal input pin
R/W=HIGH: Read operation
R/W=LOW: Write operation
D7: Serial data entry pin (SI)
D6: Serial clock input pin (SCL)
A0=HIGH: Indicates that D0 to D7 are display data.
A0=LOW: Indicates that D0 to D7 are control data.
C86=HIGH: 68 series MPU interface
C86=LOW: 80 series MPU interface
