3 WIRE, 9-BIT SPI-MODE
Pin CS0 is used for chip select and
bus cycle reset. On each write cycle,
the first bit is CD, which determines
the content of the following 8 bits of
data, MSB first. These 8 command or
data bits are latched on rising SCK
edges into an 8-bit data holder. If
CD=0, the data byte will be decoded
as command. If CD=1, this 8-bit will
be treated as data and transferred to
proper address in the Display Data
RAM at the rising edge of the
last SCK pulse. The toggle of
CS0 for each byte of data/
command is recommended
but optional. The clock-pulse
rate of the SCK line can be
up to 12 MHz.
2 WIRE, I
Pin A2 is used to configure the device address. Each I²C sequence starts with a START condition (S)
from the bus master, followed by a sequence header, containing a device address, the mode of transfer
(CD: 0=Control, 1=Data), and the direction of the transfer (RW: 0=Write, 1=Read).
Note that, for data read (CD=1), the first byte of data transmitted will be dummy.
The direction (read or write) and content type (command or data) of the data bytes following each
header byte are fixed for the sequence. To change the direction (R<>W) or the content type (C<>D),
start a new sequence with a START
(S) flag, followed by a new header.
The clock-pulse rate of the SCK line
can be up to 4 MHz.
Note that, for choosing your pullups,
the SDA and SCK pins do have an
internal resistance of 600...1000 Ohm
or more (control LO-level when
reading e.g. ACK-bit).
