PS/2 Mouse Controller
Pin Assignment
Pin Description
Pin No.

NC
No connection
2
TEST
I
If TEST is floating or connected to VSS, then the chip is under normal opera-
tion. If TEST is connected to VDD, it will operate under the TEST mode.
3
RESET
I
Input to reset internal LSI
4
OSC
I
OSC is connected to an external resistor then to VDD to generate a 6MHz sys-
tem clock.
6
CLK
I/O
Synchronous clock signal. The mouse generates a clock signal when sending
data to and receiving data from the system.
7
DATA
I/O
Bidirectional data transmission line
8
VSS
Negative power supply, ground

RB
MB
LB
I
In the non-active state these 3 switch inputs are pulled low. To activate they
must be connected to VDD.
In the TEST mode, MB, LB will indicate the condition of the X1, X2 inputs, if RB
is left floating or connected to VSS. Also in the TEST mode, if RB is connected
to VDD then MB and LB will indicate the condition of the Y1 and Y2 inputs.
