BF can be checked after the following instructions.
When BF is not checked, the waiting time between
instructions is longer than the execution instruction
time. (See Table 12.)

Important Notice
When DB3 to DB0 pins are open in 4-bit mode,
the N, RE, BE, LP bits are set to “1.” In this case,
instruction time becomes four times in a low
power mode (LP = “1”).
The low power mode is available in this step, so
instruction time takes four times.
