5.8. Display Data RAM (DD RAM)
The 80-bit DD RAM is normally used for storing display data. Those DD RAM not used for display data can be used as general data RAM. Its address is configured in the Address Counter. The relationships between Display Data RAM Address and LCDs position are depicted as follows.

5.9. Timing Generation Circuit
The timing generating circuit is able to generate timing signals to the internal circuits. In order to prevent the internal timing interface, the MPU access timing and the RAM access timing are generated independently.
5.11. Character Generator ROM (CG ROM)
Using 8-bit character code, the character generator ROM generates 5 x 8 dots or 5 x 10 dots character patterns. dots character patterns. It also can generate 192's 5 x 8 dots character patterns and 64's 5 x 10
5.10. LCD Driver Circuit
Total of 16 commons and 40 segments signal drivers are valid in the LCD driver circuit. When a program specifies the character fonts and line numbers, the corresponding common signals output drive-waveforms and the others still output unselected waveforms.
5.12. Character Generator RAM (CG RAM)
Users can easily change the character patterns in the character generator RAM through program. It can be written to 5 x 8 dots, 8-character patterns or 5 x 10 dots for 4-character patterns.

The IR can be written by MPU, but it cannot be read by MPU.
5.17. Busy Flag (BF)
When RS = 0 and R/W = 1, the busy flag is output to DB7. As the busy flag =1, SPLC780C is in busy state and does not accept any instruction until the busy flag = 0.
NMOS
5.19.3. Output port: CL1, CL2, M, D 5.18. Address Counter (AC)
The Address Counter assigns addresses to Display Data RAM and Character Generator RAM. When an instruction for address is written in IR, the address information is sent from IR to AC. After writing to/reading from Display Data RAM or Character Generator RAM, AC is automatically incremented by one (or decremented by one). The contents of AC are output to DB0 DB6 when RS = 0 and R/W = 1.

OSC1 Rf : 75.0K2% ( when VDD = 3.0V) Rf : 91K 2% ( when VDD = 5.0V) Since the oscillation frequency varies depending on the OSC1 and OSC2 pin capacitance, the wiring length to these pins should be minimized.
