    The same command is sent three times, Function Set with 8-bit interface D7–D4 = binary 0011, the lower four bits are "don't care", using single enable pulses. If the controller is in 4-bit mode, the lower four bits are ignored so they cannot be sent until the interface is in a known size configuration.
