PS/2 Keyboard and Mouse Connector (KBDMSE) (J15)
A PS/2 keyboard/mouse can be attached via the pinrow connector KBDMSE (J15). Both interfaces utilize open-drain
signalling with on-board pull-up.
In standby mode the PS/2 mouse and keyboard are supplied from SB5 V, to enable keyboard or mouse activity to
bring the system out of power saving states. The supply is provided through a 1.1 A resettable fuse.
The PS/2 connector does not support wake functions.
