5 INTERFACE WITH A HOST MICROCONTROLLER
5.1 Interface signals and operation
The interface signals between the host microcontroller and the SBN0064G are data bus and control bus. The data bus
is an 8-bit (DB0~DB7) bi-directional bus. The control bus is composed of the following signals: C/D, E, and R/W.
By means of data bus and control bus, the host microcontroller can write data to or read data from the Display Data
Memory, can program the internal registers, and can read status of the SBN0064G. It is the host microcontroller’s
responsibility to put proper data and timing on the data bus and control bus to ensure correct data transfer.
