Column Address Circuit
Column address circuit has a 8-bit preset counter that provides column address to the Display Data RAM as
shown in figure 8. When set Column Address MSB / LSB instruction is issued, 8-bit [Y7: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. However, the counter is not increased and locked if a non-existing address above 84H. It is
unlocked if a column address is set again by set Column Address MSB / LSB instruction. 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 7.
