Initializing by Instruction
If the power supply conditions for correctly operating the internal reset circuit are not met, initialization
by instructions becomes necessary.
Initializing when a length of interface is 8-bit system. (See Figure 29.)
Initializing when a length of interface is 4-bit system. (See Figure 30.)
