IL3895
1 GENERAL DESCRIPTION
IL3895 is a CMOS active matrix bistable display driver with controller. It consists of 150 source
outputs, 250 gate outputs, 1 VCOM and 1 VBD for border that can support a maximum display resolution
150x250.
IL3895 embeds booster, regulators and oscillator. Data/Commands are sent from general MCU
through the hardware selectable Serial Peripheral Interface.

6.1.3 MCU Serial Peripheral Interface (3-wire SPI)
The 3-wire SPI consists of serial clock SCLK, serial data SDIN and CS#. In SPI mode, D0 acts as SCLK, D1
acts as SDIN. The operation is similar to 4-wire SPI while D/C# pin is not used and it must be tied to LOW.
The control pins status in 3-wire SPI is shown in Table 6-3.
In the write operation, a 9-bit data will be shifted into the shift register on every clock rising edge. The bit
shifting sequence is D/C# bit, D7 bit, D6 bit to D0 bit. The first bit is D/C# bit which determines the following
byte is command or data. When D/C# bit is 0, the following byte is command. When D/C# bit is 1, the
following byte is data. Figure 6-2 shows the write procedure in 3-wire SPI
