GL901Rx 1.1
3.6 W/O EEPROM
GL901Rx can detect the EEPROM automaticly. If there is no EEPROM, GL901 use default
Genesyslogic VID (0x5e3) /PID(1207) and check the hardware pin setting for mouse type.

Description
GL901Rx ISP
Response
Setup pin =0
Command
Setup pin =1
0xFA (a) Device responds: "acknowledge" (0xFA)
0xAA (b) Enters Reset Mode.
0x00 (c) After 390ms device send 0xAA,ox00 (ID)
last package Device responds: resend the last package
0xFA Device responds: "acknowledge" (0xFA)
set the default values.
(a) Sampling rate = 100,
(b) Resolution = 4 counts/mm
(c) Scaling = 1:1
(d) Disable Data Reporting
(e) The mouse then resets its movement counters and
enters stream mode.
0xFA (a) Device responds: "acknowledge" (0xFA)
(b) Disables data reporting
(c) Resets movement counters.
This only effects data reporting in Stream mode and does
not disable sampling. Disabled stream mode functions
the same as remote mode.
0xFA (a) Device responds: "acknowledge" (0xFA)
(b) Enables data reporting
(c) Resets movement counters.
This command may be issued while the mouse is in
Remote Mode (or Stream mode), but it will only effect
data reporting in Stream mode.
0xFA Device responds with "acknowledge" (0xFA) then reads EEPROM
0xFA one more byte from the host. The GL901Rx saves this Address set
byte as the new sample rate.
command
(a) Valid sample rate: 10, 20, 40, 60, 80, 100,200
Samples/sec.
(b) Device resets movement counters.
0xFA (a) Device responds: "acknowledge" (0xFA)
0x00 (b) Standard PS2 Mouse ID = 0x00 (2D/3B)
