TIMING GENERATION CIRCUIT
Timing generation circuit generates clock signals for the internal operations.
ADDRESS COUNTER (AC)
Address Counter (AC) stores DDRAM/CGRAM/SEGRAM address, transferred from IR. After writing into (reading
from) DDRAM/CGRAM/SEGRAM, AC is automatically increased (decreased) by 1. When RS = "Low" and R/W =
"High", AC can be read through DB0-DB6
CURSOR/BLINK CONTROL CIRCUIT
It controls cursor/blink ON/OFF and black/white inversion at cursor position.
LCD DRIVER CIRCUIT
LCD Driver circuit has 34 common and 120 segment signals for LCD driving.
Data from SEGRAM/CGRAM/CGROM is transferred to 120-bit segment latch serially, and then it is stored to 120-bit
shift latch.
When each common is selected by 34-bit common register, segment data also output through segment driver from
100-bit segment latch.
In case of 1-line display mode, COM0-COM17 have 1/17 duty, and in 2-line or 4-line mode, COM0-COM33 have 1/33
duty ratio.
