CHARACTER GENERATOR ROM (CGROM)

CGROM generates 5 × 8 character pattern from character generate code in DDRAM. CGROM has 5 × 8-dot 240

character pattern including cursor position. If the data in cursor position bit are high, the data are included to the

character pattern. So, the selected positions are always "ON" regardless to cursor position. The relationship

between character code and character pattern can be referred to table 5.

TIMING GENERATION CIRCUIT

Timing generation circuit generates clock signals for the internal operations.

LCD DRIVER CIRCUIT

LCD driver circuit has 16 common and 40 segment output signals for LCD driving. Data from CGRAM/CGROM is

transferred to 40-bit segment shift register serially, then it is stored to 40-bit segment output latch. When each

com is selected by a 16-bit common register, the segment data also outputs through segment driver from 40-bit

segment output latch.

CURSOR/BLINK CONTROL CIRCUIT

It controls cursor/blink ON/OFF at the cursor position.
