Interrupt Control Register (0x1C) — Read and Write

D15

Scan Function done

0

= enabled

mask bit

1

= disabled

 

D14

Openbus Active Event

0

= enabled

true mask bit

1

= disabled

 

D13-D9

Unused

Data written to these bits has no effect

D8

Module Busy Complete

0

= enabled

1

= disabled

 

 

D7

IR ENA*

0

= writing a 0 to this bit enables interrupter capabilities

1

= writing a 1 to this bit disables interrupter capabilities

 

 

D6

IH ENA*

The module has no interrupt handler capability; therefore writing a 1 or

0 has no effect. A 1 is always read back for this bit.

 

 

 

 

The complement of the value programmed into these three bits reflects

D5-D3

Interrupter IRQ Line

the selected IRQ line used by the module. A value of 0112 would select

IRQ4, a value of 0002 would select IRQ7, and a value of 1112 would

 

 

 

 

disconnect the IRQ lines.

D2-D0

Handler IRQ Line

The module has no interrupt handler capability; therefore writing to

these bits has no effect. A 1112 is always read back for these bits.

 

 

Note that all bits in this register are set to 1 upon receipt of a hard or soft reset.

 

 

Subclass Register (0x1E) — Read Only

 

D15

VXIbus Extended

Always reads as 1.

 

Device

 

 

 

 

D14-D0

Extended Memory

Always reads as 7FFD16

 

Device

 

 

 

 

 

 

NVM Access Resister (0x20) — Read Only

 

D15-D1

Unused

 

All Bits are always 1.

 

D0

 

 

Reads back the serial data stream from the selected SMIP II board.

 

 

 

Note that only one SMIP II board may be read back at a time.

 

 

 

 

 

 

 

NVM Access Resister (0x20) — Write Only

 

D15-D2

Unused

 

Data written to these bits have no effect.

 

D1

 

 

Serial clock for the switch module; should be a logic 1 when not used.

 

D0

 

 

Serial data input for the switch module; must be a logic 1 when not

 

 

 

used.

 

 

 

 

Board X, Y Used Address Register (0x22, 0x24, 0x26) — Read and Write

D15-D8

 

Sets the actual number of words of address space used by the relays on

 

board's X.

 

 

D7-D0

 

Sets the actual number of words of address space used by the relays on

 

board's Y.
