Preliminary
COLUMN ADDRESS CIRCUIT
The column address circuit has a 9-bit preset counter that provides the column address to the display data RAM
(Shown in Table 7). When set column address MSB / LSB instruction is issued, 8 bits [Y8:Y1] are set and lowest
bit, Y0 is set to
0
. Since this address is increased by 1 at every read or write data instruction, the microprocessor
can access the display data continuously. However, the counter is not increased and locked for a non-existing
address above 108H. It is unlocked if a column address is set again by the set column address MSB / LSB
instruction. The column address counter is independent of the page address register.
ADC Select instruction makes it possible to invert the relationship between the column address and the segment
outputs. Refer to Table 6.
