Notes: 1. Data set to SEGRAM is output when COM0 and COM17 are selected, as for a 1-line display,
and output when COM0 and COM33 are selected, as for a 2-line or a 4-line display. COM0
and COM17 for a 1-line display and COM0 and COM33 for a 2-line or a 4-line display are the
same signals.
2. S1 to S96 are pin numbers of the segment output driver. S1 is positioned to the left of the
display. When the HD66712 is used by one chip, segments from S1 to S60 are displayed. An
extension driver displays the segments after S61.
3. After S80 output at 5-dot font and S96 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 SEGRAM data correspond to display selection, and zeros to non-selection.
