PS2CLK input or output?

Recommended Posts



While browsing the Arcade Megawing technical page I have noticed that on the PS/2 connectors it mentions the PS2CLK lines as output instead of input.

Now for keyboard only use I beleive PS2CLK and PS2DAT lines should be input to the FPGA, the PS2 clock signal will be generated by the keyboard. Shouldn't it be specified as input?

If we use Mouse or acknowledges then I would say it is bidirectional.

Can someone highlight why the technical page says it is output?

Hello Istvan,


Thank you for that correction! It was a mistake, you are right the keyboard does control the clock. I'm updating the page right now.


Thank you,
