Signal Name and Description
I/O Select. Fourth of four ''select'' lines driven by the
MVME162 to enable the IP. This line is used in executing input
or output cycles. IOSel* is not bussed; the signal is unique to
each IndustryPack. I/O data width is an IP-specific function; an
IP need not respond to IntSel* if it has no I/O functions.
Reserved.
Address Line 1. One of six address lines; driven by the
MVME162 to address I/O locations on the IndustryPack module
designated by the four ''select'' lines.
DMA Termination. A bidirectional line which can be used to
terminate DMA transfers. It can be asserted either by the DMA
controller or by an IndustryPack module.
Address Line 2. One of six address lines; driven by the
MVME162 to address I/O locations on the IndustryPack module
designated by the four ''select'' lines.
IP Error. Asserted by an IndustryPack module in the event of a
a non-recoverable error (e.g., component failure). Less serious
errors are signaled by interrupts.
Address Line 3. One of six address lines; driven by the
MVME162 to address I/O locations on the IndustryPack module
designated by the four ''select'' lines.
Interrupt Request 0. One of two interrupt request lines; driven
by an IndustryPack to indicate that the IP is requesting service
from the MVME162.
Address Line 4. One of six address lines; driven by the
MVME162 to address I/O locations on the IndustryPack module
designated by the four ''select'' lines.
Interrupt Request 1. One of two interrupt request lines; driven
by an IndustryPack to indicate that the IP is requesting service
from the MVME162.
Address Line 5. One of six address lines; driven by the
MVME162 to address I/O locations on the IndustryPack module
designated by the four ''select'' lines.
Function Strobe. Available for use as an input to the IP module
by a strobe or clock signal related to the bus interface logic.
