Description
Reset initializes the display.
FL low indicates an access to the Flash RAM and is unaffected by the state of address
lines A
Each location in memory has a distinct address. Address inputs (A
location in the Character RAM, the Flash RAM or a particular row in the UDC (User-
Defined Character) RAM. A

This input is used to select either an internal (CLS = 1) or external (CLS = 0) clock­ source.
Outputs the master clock­ (CLS = 1) or inputs a clock­ (CLS = 0) for slave displays.
Data is written into the display when the WR input is low and the CE input is low.
This input must be at a logic low to read or write data to the display and must go high
between each read and write cycle.
Data is read from the display when the RD input is low and the CE input is low.
The Data bus is used to read from or write to the display.
This is the analog ground for the LED drivers.
This is the digital ground for internal logic.
This is the positive power supply input.
This pin is used to measure the IC junction temperature. Do not connect.
