(3-4) Column Address
When MPU accesses the Display Data RAM, the page address (refer(3-3) ) and column address set are
required before the data writing. The column address set requires twice address set which are higher order 4
bits address set and lower order 4 bits. When the MPU accesses the Display Data RAM sequentially, the
column address is increase one by one automatically, therefore, the MPU can access only the data sequen-
tially without address set.
After writing 1page data, page address setting is required due to page address doesn't increase automatically.
The increment of the column address is stopped at the address of (83)
H
not changed even if the column address increase to (83)
changed.

BUSY : BUSY=1 indicate the operating or the Reset cycle.
The instruction can be input after the BUSY status change to "0".
ADC : Indicate the output correspondence of column (segment) address and segment driver.
0 :Counterclockwise Output (Inverse) Column Address 131-n <---> Segment Driver n
1 :Clockwise Output (Normal) Column Address n <---> Segment Driver n
(Note) The data "0=Inverse" and "1=Normal" of ADC is inverted with the ADC select
Instruction of "1=Inverse" and "0=Normal".
ON/OFF : Indicate the whole display On/Off status.
0 : Whole Display "On
1 : Whole Display "Off"
(Note) The data "0=On" and "1=Off" of Display On/Off status read out is inverted with the
Display On/Off instruction data of "1=On" and "0=Off".
RESET : Indicate the initializing by RES signal or reset instruction.
