SEGRAM has a capacity of 8
×
6 bits, for controlling the display of a maximum of 40 (48 in the 6-dot font
width) icons and marks. While COMS1 and COMS2 outputs are being selected, SEGRAM is read and
segments (icons and marks) are displayed by a multiplexing drive method (20 segments each during
COMS1 and COMS2 selection).
Bits in SEGRAM corresponding to segments to be displayed are directly set by the MPU, regardless of the
contents of DDRAM and CGRAM.
Tables 9 and 10 illustrate the correspondence between SEGRAM addresses and driver signals.

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 SEG20 data is identical to SEG21 to SEG40 and SEG41 to SEG60 data.
3. The lower five bits (D4 to D0) of SEGRAM data determine on or off display of each segment. A
segment is selected (turned on) when the corresponding data is 1, and is deselected (turned off)
when the corresponding data is 0. The upper three bits (D7 to D5) are invalid.
