Return Home
The return home instruction (Figure 6) sets DDRAM address 0 into the address counter. The DDRAM
contents do not change.The cursor or blinking goes to the top left of the display.
Start Oscillator
The start oscillator instruction (Figure 7) re-starts the oscillator from a halt state in standby mode. After
issuing this instruction, wait at least 10 ms for oscillation to become stable before issuing the next
instruction. (Refer to the Standby Mode section.)
Entry Mode
The entry mode instruction (Figure 8) includes the I/D and OSC bits.
I/D:
Increments (I/D = 1) or decrements (I/D = 0) the DDRAM address by 1 when a character code is
written into or read from DDRAM.The cursor or blinking moves to the right when incremented by 1 and
to the left when decremented by 1. The same applies to writing and reading of CGRAM and SEGRAM.
OSC:
Divides the external clock frequency by four (OSC = 1) using the resulting clock as an internal
operating clock. The execution time for this instruction and subsequent ones is therefore quadrupled. The
execution time of clearing this bit (OSC = 0) is also quadrupled. (For application of this instruction, refer
to the Partial-Display-Off Function section.)
