Chip operates on horizontal pixel lines (8 pixels in line), so we use 8 data pins and 3 address line pins instead of 64 data pins

Selecting the line:
Top line at the address 0, (ADDR0 = 0, ADDR1 = 0, ADDR2 = 0)
Second top line at the address 1, (ADDR0 = 1, ADDR1 = 0, ADDR2 = 0)
Bottom top line at the address 7, (ADDR0 = 1, ADDR1 = 1, ADDR2 = 1)

Chip has buffer memory and display memory, so you can write multiple lines separately and then push data to display

CE - Chip Enable, when off no writes possible and pixel won't light up, when on - operate normally (may be redundant)
WE - Write Enable, write data to buffer
ADDR0,1,2 - Address Bits, Active line address bits
PUSH - Push data from buffer memory to display memory
0-7 - Data pins
