Notes: 1. When the SFT pin is grounded, the SEG1 pin output is connected to the far left of the LCD
panel, and when the SFT pin is high, the SEG60 pin output is connected to the far left.
2. SEG1 to SEG24 data are identical to SEG25 to SEG48 and SEG49 to SEG60 data.
3. The lower six bits (D5 to D0) of SEGRAM data determine on or off display for each segment. A
segment is selected (turned on) when the corresponding bit is 1, and is deselected (turned off)
when the corresponding bit is 0. The upper two bits (D7 to D6) are invalid.
Timing Generation Circuit
The timing generation circuit generates timing signals for the operation of internal circuits such as
DDRAM, CGROM, CGRAM, and SEGRAM. RAM read timing for display and internal operation timing
by MPU access are generated separately to avoid interfering with each other. Therefore, when writing data
to DDRAM, for example, there will be no undesirable interferences, such as flickering, in areas other than
the display area.
Cursor/Blink Control Circuit
The cursor/blink (or white-black inversion) control is used to produce a cursor or a flashing area on the
display at a position corresponding to the location stored in the address counter (AC).
