8.1.3 MPU Serial Interface
The serial interface consists of serial clock SCLK, serial data SDIN, D/C#, CS#. In SPI mode, D0 acts as
SCLK, D1 acts as SDIN. For the unused data pins, D2 should be left open. The pins from D3 to D7, E and
R/W# can be connected to an external ground.
SDIN is shifted into an 8-bit shift register on every rising edge of SCLK in the order of D7, D6, ... D0. D/C#
is sampled on every eighth clock and the data byte in the shift register is written to the Graphic Display Data
RAM (GDDRAM) or command register in the same clock.
Under serial mode, only write operations are allowed. And during data writing, an additional NOP command
should be inserted before the CS# goes HIGH as shown in Figure 8-3
