Super I/O

The used Super I/O is a Standard Microsystems Corporation LPC47S422 device. It
provides the following interfaces:

aa

S Two serial interfaces

S Floppy disk interface

S Keyboard/Mouse interface

S Parallel interface

Serial Interfaces

The Super I/O device provides two serial full−duplex RS232 interfaces. Supported baud
rates are: 600, 1200, 2400, 4800, 9600, 19200, 38400 and 115200 kb/s. Both serial interfaces
are +/− 15 KV ESD protected.

Both interfaces correspond to the blade

′s serial interface ports 2 and 4. Serial interface port

2 is routed via a zone 3 connector to an installed RTM. Serial interface port 4 is accessible
via an installed CMC module. The BIOS maps the serial interface ports to the desired I/O
addresses (COM ports) and interrupts.

Floppy Disk Interface

The floppy disk interface is unused on the blade.

a

Keyboard/Mouse Controller

The Super I/O integrates an 8042H compatible keyboard/mouse controller. The
corresponding interfaces are accessible via RTM and CMC debug module.

a

Parallel Interface

The parallel interface is unused on this blade.
