8.4
This module determines whether the input data is interpreted as data or command. Data is interpreted based
upon the input of the D/C# pin.
If D/C# pin is HIGH, [7:0] is treated as either the data bytes of multiple byte command or display data written
to Graphic Display Data RAM (GDDRAM). If it is LOW, the input at D[7:0] is interpreted as a command.
Then data input will be decoded and written to the corresponding command register.
8.5
When RES# input is LOW, the chip is initialized with the following status:

This block is used to derive the incoming power sources into the different levels of internal use voltage and
current. V
drivers.
8.7
There are 64 segment drivers as the current sources to hard icons and 2 common drivers with 2 pins each to
sink the current. The hard icons drivers support either DC or AC driving method.
8.8
It is a 2X charge-pump type voltage generator circuit. It doubles the voltage input V

8.9
In SSD1329 there are 16 gray levels from GS0 to GS15. The gray scale of the display is defined by the pulse
width (PW) of current drive phase, except GS0 there is no pre-charge (phase 2,3) and current drive (phase 4).
