Function Set RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 0 0 0 1 DL 1 0 FT1 FT0 DL = Interface Data Length When DL = “1”, the data is sent or received in 8‐bit length via DB7..DB0. When DL = “0”, the data is sent or received in 4‐bit length via DB7..DB4. When the 4‐bit data length is used, the data must be sent or received in two consecutive writes/reads to combine the data into full 8‐bits.
