The MTC is responsible for the following tasks and components:
•

8.20.1 AT Keyboard (PS/2)
As shown in the block diagram, the keyboard is not directly operated by the keyboard controller
in the I/O controller, but rather by the MTC. It is therefore possible to plug an AT keyboard in and
out while the IPC is switched on (Hot Plug). Furthermore, the AT keyboard can be operated
parallel to connected keypad modules or to a keyboard on a display unit (see the next section).
