Annunciator/SEGRAM Address Set
The annunciator/SEGRAM address set instruction (Figure 17) includes the DA and A bits.
DA:
Turns annunciator display on or off. When DA = 1, annunciator display is turned on and driven
statically. When DA = 0, annunciator display is turned off with ASEG1 to ASEG10 and ACOM pins held
to V
CC
level.
The internal operating clock supply is halted during standby mode; make sure to turn off display (DA =
0) if the external alternating signal is not supplied. Refer to the Segment Display and Annunciator
Display section and the Standby Mode section.
AAAA:
Used for setting the SEGRAM address in the address counter (AC) or for setting an annunciator
address. The SEGRAM addresses range from 1000H to 1111H (8 addresses), while the annunciator
addresses range from 0000H to 0010H (3 addresses).
The annunciator address is directly set without using the address counter, and consequently must be
updated for each access. The annunciator address can be set even during sleep and standby modes.
Once the SEGRAM address is set, data in the SEGRAM can be accessed consecutively since the address
counter is automatically incremented or decremented by one according to the I/D bit setting after each
access. The SEGRAM address cannot be set during sleep or standby mode.
