Clear Display (R0)
The clear display instruction writes half-size space code A0H (half-size HCROM for character code A0H
must be a blank pattern) into all DDRAM addresses. It then sets DDRAM address 0 into the address
counter (AC). It also sets I/D to 1 (increment mode) in the entry mode set instruction. Since the execution
time of this instruction needs 85 clock cycles, do not transfer the next instruction during this time.

Start Oscillation (R1)
The start oscillation instruction restarts the oscillator from the halt state in the standby mode. After issuing
this instruction, wait at least 10 ms for oscillation to stabilize before issuing the next instruction. (See the
Standby Mode section.)
