Product data sheet
9.1 Clear display
Table 11.
‘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 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.
