10 PARALLEL INTERFACES
The parallel interfaces that can be selected are the
6800-type and 8080-type 8-bit bidirectional interface for
communication between the microcontroller and the LCD
driver chip. The selection of an interface is done with
inputs PS2, PS1 and PS0, see Table 16.
10.1
6800-type parallel interface
The interface functions of the 6800-type parallel interface
are shown in Table 19. Figures 24 to 29 show the data
transfer in different modes. The transmission byte (TB)
shown in these figures is a register value or a control byte,
depending on the mode and protocol used.
