Annunciator Display Function
The HD66410 can display up to 72 dots of annunciator using 24 segment (column) drivers (SEG1 to
SEG24) and three common (row) drivers (COM1 to COM3). These drivers, independent of the display
RAM, operate statically or with a 1/3 duty cycle. They are available even during standby modes, where
dot-matrix display and the internal booster is turned off, making them suitable for time and other mark
indications with reduced power dissipation.
The dots to be displayed are designated by annunciator display data registers 1 to 9. For static drive, only
display data registers 1, 3, and 7 and row driver COM1 are used. A maximum of 18 turned-on dots can be
blinked. For details on blinking, see the Blink Function section. Figure 21 shows the relationship between
annunciator display data register bits and display positions. In the figure, alphanumerics in the ovals
indicate the bit names of annunciator display data registers. Data value 1 turns on the corresponding dot on
the panel, and data value 0 turns off the corresponding dot. Table 2 lists the annunciator display data
registers.
