Openbus Active

The Openbus was activated by one or more programmed inputs.

See description of the Openbus in the module register section.

 

 

 

D13 = Module 5, … and D8 = Module 0.

D13-D8

Modules 0-5 Busy

The programmed Busy signal from one of the modules has timed

have settled and a measurement may take place.

D7-D0

Reserved

Always reads back as FFFF16

Note: This status register may be used in a polled fashion rather than allowing the events above to generate an Interrupt. A read of this register will clear any active bits. Bits that are not set, or are about to be set, are not affected by a read of this register.

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.

 

 

 

Interrupter IRQ

The complement of the value programmed into these three bits

D5-D3

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

Line

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

 

 

 

value of 1112 would disconnect the IRQ lines.

 

 

The module has no interrupt handler capability; therefore writing

D2-D0

Handler IRQ Line

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 1s upon receipt of a hard or soft reset.
