I Dimension select : NC = 3D , tied to Pin15 = 2D Internal pull down resistor = 10K ohm
Valid when No EEPROM exists
Please Tight to LED (pin17) or open
I
Buttons select : NC = 3B , tied to pin15 = 5B Internal pull down resistor = 10K ohm
Valid when No EEPROM exists
Please Tight to LED (pin17) or open
I/O PS2 : Output High
USB : Input = Floating
I/O PS2: Clock open drain pin
USB :D+
I/O PS2: Data pin
USB :D-
PS2 interface is detected : PS2En will
be set output high for the pull up
source of PS2 CLK pin
USB interface is detected : PS2En will
be floating
Need 1 7.5K pull up resistor to PS2En
Need a 7.5K Pull up resistor to 5V or
1.5K to 3.3V
