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 5V_STB 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.
