6.3 PS/2 Keyboard and Mouse connector (KBDMSE) (J27)

Attachment of a PS/2 keyboard/mouse can be done through the pinrow connector KBDMSE (J27).

Both interfaces utilize open-drain signalling 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 resettable fuse.
