CLOCK SELECT
(CLS, pin 11)
Used to select either an internal (CLS = 1) or external (CLS = 0) clock source.
CLOCK INPUT/OUTPUT
(CLK, pin 12)
Outputs the master clock (CLS = 1) or inputs a clock (CLS = 0) for slave
displays.
WRITE (WR, pin 13)
Data is written into the display when the WR input is low and the
CE input is low.
CHIP ENABLE (CE, pin 17)
Must be at a logic low to read or write data to the display and must go
high between each read and write cycle.
READ (RD, pin 18)
Data is read from the display when the RD input is low and the CE
input is low.
