(7) Read Display Data
Reads 8-bits of data from the data I/O latch, updates the contents of the I/O buffer with display data from the display data
RAM location specified by the contents of the column address and page address registers and increments the column
address register.
After loading a new address into the column address register, one dummy read is required before valid data is obtained.
(8) Select ADC
Selects the relationship between display data RAM column addresses and segment drivers.
D=1: SEG0

This command is provided to reduce restrictions on the placement of driver ICS and routing of traces during printed circuit
board design. See figure 2 for a table of segments and column addresses for the two values of D.

D=1: Static drive on
D=0: Static drive off
