Column Address Circuit
Column address circuit has a 7-bit preset counter that provides column address to the Display Data RAM as shown
in
Figure 11
. When set Column Address MSB / LSB instruction is issued, 7-bit [Y6:Y0] is updated. And, since this
address is increased by 1 each a read or write data instruction, microprocessor can access the display data
continuously. And the Column Address counter is independent of page address register.
ADC Select instruction makes it possible to invert the relationship between the column address and the segment
outputs. It is necessary to rewrite the display data on built-in RAM after issuing ADC Select instruction. Refer to the
following Figure 10.

Segment Control Circuit
This circuit controls the display data by the Display ON / OFF, reverse display ON / OFF and entire display ON / OFF
instructions without changing the data in the display data RAM.
