4.3 Keyboard and PS/2 mouse connectors

Attachment of a keyboard or PS/2 mouse adapter can be done through the stacked PS/2 mouse and

keyboard connector (MSE & KBD).

Both interfaces utilize open-drain signaling with on-board pull-up.

The PS/2 mouse and keyboard is supplied from SB5V when in standby mode in order to enable keyboard or

mouse activity to bring the system out from power saving states. The supply is provided through a 1.1A

resetable fuse.
