This bit is a read-only status bit that reflects the state of DATA11 during reset.
This field determines what the EBI does with the external bus during internal transfer operations. A
show cycle allows internal transfers to be externally monitored. The table below shows whether show
cycle data is driven externally, and whether external bus arbitration can occur. To prevent bus conflict,
external peripherals must not be enabled during show cycles.
The SUPV bit places the SIM global registers in either supervisor or user data space.
Each module that can generate interrupt requests has an interrupt arbitration (IARB) field. Arbitration
between interrupt requests of the same priority is performed by serial contention between IARB field bit
values. Contention must take place whenever an interrupt request is acknowledged, even when there
is only a single pending request. An IARB field must have a non-zero value for contention to take place.
If an interrupt request from a module with an IARB field value of %0000 is recognized, the CPU pro-
cesses a spurious interrupt exception. Because the SIM routes external interrupt requests to the CPU,
the SIM IARB field value is used for arbitration between internal and external interrupts of the same pri-
ority. The reset value of IARB for the SIM is %1111, and the reset IARB value for all other modules is
%0000, which prevents SIM interrupts from being discarded during initialization.
