6. FUNCTIONAL DESCRIPTION
Microprocessor Interface
Interface type selection
The S1D15A06 series can transfer data via 8-bit bi-
directional data buses (D7 to D0) or via serial data input
(SI). Through selecting the P/S pin polarity to the HIGH
Parallel interface
When the parallel interface has been selected (P/S
=HIGH), then it is possible to connect directly to either
Serial interface
When the serial interface has been selected (P/S=LOW)
then when the chip is in active state(CS=LOW) the
serial data input (SI) and the serial clock input (SCL)
can be received.
The serial data is read from the serial data input pin in
the rising edge of the serial clocks D7, D6 through D0,
in this order. This data is converted to 8 bits parallel data
in the rising edge of the eighth serial clock for the
processing.
Rev. 1.0a
Moreover, the S1D15A06 series identifies the data bus
signal according to A0, RD(E), WR(R/W)signals, as

shown in Table 3.
The A0 input is used to determine whether the serial
data input is display data or command data; when
A0=HIGH, the data is display data, and when A0=LOW
then the data is command data.
The A0 input is read and used for detection every 8th
rising edge of the serial clock after the chip becomes
active.
