Interface Table

This field contains the I/O card address representing the I/O slot number that the MUX interface card is installed in. It is initialized by TTGEN from the slot value specified in the MUX statement of the TTGEN configuration file.

INHPA - Interface HPA value (from TTGEN)

The HPA value is built as follows:

For the Mux interface in an HP-PB standard backplane, the card address is 4 x slot number. In the TTGEN configuration file, the card address is given as BUS:SLOT (e.g., 0:48), or BUS:BUS:SLOT. Here the 10-bit Bus Address field is translated from the 1’s complement of BUS (i.e.,

1023-BUS). The Slot field is specified by SLOT/4. The Module, Page, Register Set, and Reg No. fields are set to 0. For the example of BUS:SLOT=0:48, the HPA is 0xFFFB0000. For EISA standard backplanes the address is the slot number.

IFTYPE - Interface card type

Specified in TTGEN through the interface definition (the keyword MUX) with the following results:

IFTYPE

= ZCOM_ITYPE_Z7200A(6)

-

Z7200A HP-PB

ACC 8-channel Mux

IFTYPE

= ZCOM_ITYPE_Z7350A(7)

-

Z7350A HP-PB

ACC 2-channel Mux

IFTYPE

= ZCOM_ITYPE_Z7400A(8)

-

Z7400A EISA

ACC 8-channel Mux

IFTYPE

= ZCOM_ITYPE_Z7300A(9)

-

Z7300A HP-PB

ACC 4-port E1/T1

IFTYPE

= ZCOM_ITYPE_Z7330A(10)

- Z7330A PCI

ACC 4-port E1/T1

IFTYPE

= ZCOM_ITYPE_Z7340A(11) -

Z7340A PCI

ACC 8-channel Mux

This field allows for the future support of extra interface types.
