9) Function Set
c
(RE = 0)
DL : Interface data length control bit
When DL = "High", it means 8-bit bus mode with MPU.
When DL = "Low", it means 4-bit bus mode with MPU. Hence, DL is a signal to select 8-bit or 4-bit bus mode.
In 4-bit bus mode, it is required to transfer 4-bit data twice.
N : Display line number control bit
It is variable only when NW bit of extended function set instruction is Low.
When N = "Low", it means 1-line display mode.
When N = "High", 2-line display mode is set.
When NW = "High", N bit is invalid, it means 4-line mode independent of N bit.
RE : Extended function registers enable bit
At this instruction, RE must be "Low".
DH : Display shift enable selection bit.
When DH = "High", enable display shift per line.
When DH = "Low", enable smooth dot scroll.
This bit can be accessed only when IE pin input is "High".
REV : Reverse enable bit
When REV = "High", all the display data are reversed. I.e., all the white dots become
black and black dots become white.
When REV = "Low", the display mode set normal display.
