Controller Information
Built‐in SSD1963 controller
Please download specification at http://www.newhavendisplay.com/app_notes/SSD1963.pdf
MCU Interface
The controller board operates in 8080 mode. This interface uses /WR to define a write cycle and /RD for read cycle. If
/WR goes low when the /CS signal is low, the data or command will be latched into the system at the rising edge of /WR.
Similarly, the read cycle will start when /RD goes low and end at the rising edge of /RD.
