9.4 Display Clear (C/D= "1")
This command should always be applied at power on or reset. In the period of 1mS following the
issue of this command, the module requires internal processing and does not accept any
commands.
To clear the GRAM area, G1C or G0C bit must be asserted. By asserting HM bit, both data write position
address and display start position address which selected by G1C, G0C, DC also be reset.
HM = (1 or 0) equals (Initialize data write position address and display start position address or Not initialize).
9.3 Cont’d
Brightness levels are set by the following:
G1C= (1 or 0) equals (GRAM area 1 is cleared or GRAM area 1 not cleared)
G0C= (1 or 0) equals (GRAM area 0 cleared or GRAM area 0 not cleared)
GRAM area 1: X= 00H-7FH, Y=0H – 7H (Display data write position address)
GRAM area 2: X= 00H-7FH, Y=8H – FH (Display data write position address)
