Note1 : Address 2 : High nibble presents dimension number and low nibble presents button number.
These setting will affect USB & PS2 report data format to the host.
[D3:D0] = Dimension number . Valid Setting : 2=2D , 3=3D, 4=4D,
[B3:B0] = Buttons number Valid Setting : 1=1B, 2=2B, 3=3B, 4=4B , 5=5B
Genesyslogic suggests to use 2D3B , 3D3B , 3D5B setting.
Note2 : Mark area is not available now.
I2c EEPROM ISP Procedure (For Manufacturing)
GL901Rx can do “In System Program” directly through PS2 command when GL901Rx Setup pin is
set high. GL901Rx use only 3 commands to control the R/W of EEPROM.
(a) 0xF3 : Set current EEPROM Address pointer.
(b) 0xE8: Set Data and execute EEPROM write to current Address pointer then increase EEPROM
Address pointer.
(c) 0xEB: Read EEPROM 8 bytes from current Address pointer
