Super I/O
The used Super I/O is a Standard Microsystems Corporation LPC47S422 device. It provides the following interfaces:aa
STwo serial interfaces
SFloppy disk interface
SKeyboard/Mouse interface
SParallel 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.aaaaa
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.
