XVME-560 Manual
September, 1984
The module status/control register (found at module base a 8lH) on intelligent
XVME I/O modules provides the current status of the module self-test in conjunction
with the current status of the front panel LEDs.
The status register on intelligent
modules is a “Read Only” register and it can be read by software to determine if the
board is operating properly.
On non-intelligent XVME I/O modules, the status/control register is used to indicate
the state of the front panel LEDs, and to set and verify module-generated interrupts.
The LED status bits are " R e a d / W r i t e " locations which provide the user with the
indicators to accomodate diagnostic software. The Interrupt Enable bit is also a
Read/Write location which must be written to in order to enable module-generated
interrupts.
The Interrupt Pending bit is a “Read Only” bit which indicates a module-
generated pending interrupt.
