8.1 Clear display

‘Clear display’ writes character code 20H into all DDRAM

addresses (the character pattern for character code 20H

must be a blank pattern), sets the DDRAM address

counter to logic 0 and returns the display to its original

position, if it was shifted. Thus, the display disappears and

the cursor or blink position goes to the left edge of the

display. Sets entry mode I/D = 1 (increment mode). S of

entry mode does not change.

The instruction ‘clear display’ requires extra execution

time. This may be allowed by checking the Busy Flag (BF)

or by waiting until the 165 clock cycles have elapsed.

The latter must be applied where no read-back options are

foreseen, as in some Chip-On-Glass (COG) applications.

8.2 Return home

‘Return home’ sets the DDRAM address counter to logic 0

and returns the display to its original position if it was

shifted. DDRAM contents do not change. The cursor or

blink position goes to the left of the first display line.

I/D and S of entry mode do not change.
