MPU Interface
For detailed timing information, see datasheet: http://www.newhavendisplay.com/app_notes/SSD1305.pdf
6800‐MPU Parallel Interface
The parallel interface consists of 8 bi‐directional data pins, R/W, D/C, E, and /CS.
A LOW on R/W indicates write operation, and HIGH on R/W indicates read operation.
A LOW on D/C indicates “Command” read or write, and HIGH on D/C indicates “Data” read or write.
The E input serves as data latch signal, while /CS is LOW. Data is latched at the falling edge of E signal.
8080‐MPU Parallel Interface
The parallel interface consists of 8 bi‐directional data pins, /RD, /WR, D/C, and /CS.
A LOW on D/C indicates “Command” read or write, and HIGH on D/C indicates “Data” read or write.
A rising edge of /RS input serves as a data read latch signal while /CS is LOW.
A rising edge of /WR input serves as a data/command write latch signal while /CS is LOW.
Alternatively, /RD and /WR can be kept stable while /CS serves as the data/command latch signal.
