SYSTEM_INT_IDX
R
W
Undefined
Lowest CM0+ activated system interrupt index for CPU
interrupt 0.
Multiple system interrupts can be mapped on the same
CPU interrupt. The selected system interrupt is the
system interrupt with the lowest system interrupt index
that has an activated interrupt request at the time of
the fetch (system_interrupts[SYSTEM_INT_IDX] is '1').
The CPU interrupt handler SW can read
SYSTEM_INT_IDX to determine the system interrupt
that activated the handler.

0
Valid indication for SYSTEM_INT_IDX. When '0', no
system interrupt for CPU interrupt 0 is valid/activated.
