4. Timing Generator Circuit
This circuit generates the timing signal for the internal operation by CPU's instruction as well
as to operate the internal circuit of DD RAM, CG RAM, CG ROM and so forth. It also generates
the transfer signal to the SEGMENT driver (MSM5839C or MSM5259).
The internal operation accessed by the CPU and internal operation for LCD display is
independent.
So, a manipulation such as writing data from CPU to DD RAM will not have an influence such
as display flickering upon any part other than the display part to which the data is written.
5. Display Data RAM (DD RAM)
DD RAM is used to store the 8-bit character code (refer to Table 1) and 1-bit under-line data.
The address of DD RAM corresponds to the display position on the LCD. The correspondence
is described below.
DD RAM address (set to ADC) is described as hexadecimal.
