LCD Interface

LCD panels are popular peripherals for 8-bit systems. Those with
Hitachi controllers are easy to control, needing either 7 or 11 pins for
a 4- or 8-bit interface.

The 4-bit interface requires some extra software to split command and data words, and to send and receive bytes in two nibbles.
