RS = 0; R/W = 0; DB7 = 0; DB6 = 0; DB5 = 1; DB4 = 1
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’ (set interface to 4-bits long). Interface is 8-bits long.
‘Function set’ (interface is 4-bits long).
Specify number of display lines and voltage generator characteristic.
