Functional Description
3
The MCP750HA supports one PMC slot. Four 64-pin connectors on the
base board (J11, J12, J13, and J14) interface with 32-bit or 64-bit IEEE
P1386.1 PMC-compatible mezzanines to add any desirable function. The
PCI Mezzanine Card slot has the following characteristics:
Refer to
Chapter 4, Connector Pin Assignments
, for the pin assignments of
the PMC connectors. For additional programming information, refer to the
PCI bus descriptions in the MCP750 Single Board Computer
Programmer's Reference Guide, listed in
, and to the user documentation for the PMC modules that
you intend to use.
PC97307 ISA Super I/O Device
The MCP750HA uses the PC97307 ISA Super I/O device from National
Semiconductor to provide the following:
❏
Two asynchronous serial ports
❏
Parallel port via transition module
❏
Floppy disk drive support via transition module
❏
A PS/2 keyboard and mouse interface via transition module
❏
A parallel printer port interface
Asynchronous Serial Ports
The Super I/O device provides two UART devices which are compatible
with standard 16450 or 16550A UARTs. The default configuration assigns
COM1 to IRQ4 and COM2 to IRQ3 of the PBC. The default configuration
can be changed by programming the ISA Super I/O device accordingly.
