SEGRAM data
Blinking control
Pattern on/off
a) 5-dot font width
b) 6-dot font width
Notes: 1. Data set to SEGRAM is output when COM17 is selected, as for a 1-line display, and output
when COM33 is selected, as for a 2-line or a 4-line display.
2. S1 to S48 are pin numbers of the segment output driver.
S1 is positioned to the left of the monitor.
S37 to S48 are extension driver outputs for a 6-dot character width.
3. After S40 output at 5-dot font and S48 output at 6-dot font, S1 output is repeated again.
4. As for a 5-dot font width, lower five bits (D4 to D0) are display on.off information of each
segment. For a 6-dot character width, the lower six bits (D5 to D0) are the display information
for each segment.
5. When the BE bit of the function set register is 1, pattern blinking of the lower six bits is
controlled using the upper two bits (bits 7 and 6) in SEGRAM.
When bit 7 is 1, only a bit set to “1” of the lower six bits is blinked on the display.
When bit 6 is 1, only a bit 4 pattern can be blinked as for a 5-dot font width, and only a bit 5
pattern can be blinked as for 6-dot font width.
6. Bit 5 (D5) is invalid for a 5-dot font width.
7. Set bits in the CGRAM data correspond to display selection, and zeros to non-selection.
