(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 the specified instruction time (see Table 3).
‘Function set’ (interface is 8-bits long). Specify the number of display lines.
‘Display off’.
‘Clear display’.
‘Entry mode set’.
