Note:
The annunciator is turned on when the corresponding even bit (bit 6, 4, 2, or 0) is 1, and the turned-
on annunciator blinks when the corresponding odd bit (bit 7, 5, 3, or 1) is 1.

Note: If annunciator display is unnecessary during standby mode, make sure to fix the EXM pin to the V
CC
or GND level
and set the annunciator display ON bit (DA) to 0. This will prevent dark display and liquid-cell deterioration due to
DC bias application on liquid crystal cells.
