BF can not 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 execution instruction time.
Function set ( Set interface to be 4 bits long. )
Interface is 8 bits in length.
Function set ( Interface is 4 bits long. Specify
the number of display lines and character font. )
The number of display lines and character font
can not be changed after this point.
