Tested mode 1 (default 8-bit mode), and mode 2 (8-bit mode with
arbitrary pins for the data lines).
Signed-off-by: Collin J. Doering <collin.doering@rekahsoft.ca>
1. Default mode (8-bit data bus, control lines on any PINs)
2. 8-bit arbitrary pin mode (8-bit data bus on any PIN, control lines on
any PINs)
3. 4-bit mode (4-bit data bus, control lines on any PINs)
Default mode is tested and working. The others still require testing.
