Initializing by Instruction
If the power supply conditions for correctly operating the internal reset circuit are not met, initialization by
instructions becomes necessary.
Refer to Figures 24 and 25 for the procedures on 8-bit and 4-bit initializations, respectively.

BF cannot be checked before this instruction.
Function set (Interface is 8 bits long.)
BF cannot be checked before this instruction.
Function set (Interface is 8 bits long.)
BF can be checked after the following instructions.
When BF is not checked, the waiting time between
instructions is longer than the execution instuction
time. (See Table 7.)
Function set (Interface is 8 bits long. Specify the
number of display lines and character font.)
The number of display lines and character font
cannot be changed after this point.
