Preliminary
COLUMN ADDRESS CIRCUIT
Column address circuit has a 7-bit preset counter that provides column address to the display data RAM (shown in
Table 7). When Set Column Address MSB / LSB instruction is issued, 7-bit [Y6:Y0] is updated. Since this address
is increased by 1 each time there is a Read or Write Data instruction, the microprocessor can access the display
data continuously. However, the counter is not increased and it is locked at a non-existing address above 63H. It is
unlocked if a column address is set again by Set Column Address MSB/LSB instruction. 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. Refer to the following Table 6.
