CLOCK
I/O Bi-directional signal line between EC3592R and
PC system. Whenever the mouse is ready to send
data
to the system or the system wants to send command
to the mouse, it will clock in 11 bits of CLOCK on
this line.
DATA I/O

open-drain output with internal pull-up resistor. All
mouse data and system commands are transmitted
through this line.

Right button selection. Built-in pull-down resistor
of 50K BR pin is HIGH when right button is
pressed and becomes LOW when it is released.
EC3592R has edge-triggered button operation. It
will only report through DATA line on a rising
edge or falling edge of the input signal.
BM I
Middle button selection. Built-in pull-down resistor
of 50K. It is also edge-triggered button operation
as "BR".

50K. It is also edge-triggered button operation as
"BR".
