DESCRIPTION
Power-on or unknown state
|
Wait 2 ms after VDD rises above VPOR
|
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).

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).

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 specied instruction time (see Table 3).
RS = 0; R/W = 0; DB7 = 0; DB6 = 0; DB5 = 1; DB4 = 0
‘Function set’ (set interface to 4-bits long). Interface is 8-bits long.
RS = 0; R/W = 0; DB7 = 0; DB6 = 0; DB5 = 1; DB4 = 0
‘Function set’ (interface is 4-bits long).
RS = 0; R/W = 0; DB7 = N; DB6 = M; DB5 = 0; DB4 = 0
Specify number of display lines and voltage generator characteristic.
RS = 0; R/W = 0; DB7 = 0; DB6 = 0; DB5 = 0; DB4 = 0
‘Display off’.
RS = 0; R/W = 0; DB7 = 1; DB6 = 0; DB5 = 0; DB4 = 0
RS = 0; R/W = 0; DB7 = 0; DB6 = 0; DB5 = 0; DB4 = 0
‘Clear display’.
RS = 0; R/W = 0; DB7 = 1; DB6 = 0; DB5 = 0; DB4 = 0
RS = 0; R/W = 0; DB7 = 0; DB6 = 0; DB5 = 0; DB4 = 0
‘Entry mode set’.
RS = 0; R/W = 0; DB7 = 0; DB6 = 1; DB5 = I/D; DB4 = S
