3.8.2 System Status Bits
The eight most significant bits of the SCR are used to report events recognized by the sys-
tem control logic. On recognition of an event, this logic sets the corresponding bit in the
SCR. The bits may be read at any time. A bit is reset by one and is left unchanged by zero.
More than one bit may be reset at a time.
After system reset (simultaneous assertion of RESET and HALT), these bits are cleared.
IPA—Interrupt Priority Active
MOTOROLA
This bit is set when the M68000 core has an unmasked interrupt request. When bus clear
mask (BCLM) is set, BCLR and the internal bus clear to the IDMA are asserted.
If BCLM is set, an interrupt handler will normally clear IPA at the
end of the interrupt routine to allow an alternate bus master to
regain the bus; however, if BCLM is cleared, no additional action
need be taken in the interrupt handler.
In the case of nested interrupts, the user may wish to clear the
IPA bit only at the end of the original lower priority interrupt rou-
tine to keep BCLR asserted until it completes. To guarantee that
