Each interrupt request from external lines and from USIU internal interrupt sources in the case of its
assertion will set a corresponding bit in SIPEND register. The individual SIPEND bits may be masked by
clearing an appropriate bit in SIMASK register.
6.1.4.4
The enhanced interrupt controller operation may be turned on by setting the EICEN control bit in the
SIUMCR register. In this mode the 32 IMB interrupt levels will be latched by USIU using eight IMB
interrupt lines and two lines of ilbs via the time multiplexing scheme defined by the UIMB module. In
addition to the IMB interrupt sources the external interrupts and timer interrupts are available in the same
way as in the regular scheme. In this mode, the UIMB module does not drive U-bus interrupt level lines.
Each interrupt request will set a corresponding bit in SIPEND2 or SIPEND3 registers. SIPEND2 an
SIPEND3 may be masked by clearing an appropriate bit in SIMASK2 or SIMASK3 registers.
The priority logic is provided in order to determine the highest unmasked interrupt request, and interrupt
code is generated in the SIVEC register. See

Enhanced Interrupt Controller Operation
If the enhanced interrupt controller is enabled, a delay is required prior to
re-enabling interrupts. Before clearing an interrupt related register, clear the
MSR[EE] bit (EE = 0). Expect a vector offset of 0x0 if an interrupt is cleared
or disabled while MSR[EE] = 1. This vector should be handled as if no
interrupt has occured, that is, perform an rfi instruction. After clearing an
interrupt source, sufficient time must elapse before re-enabling the
MSR[EE] bit (EE = 1). This time should take longer than the time needed
for a load of the same register that was just cleared. To guarantee enough
time, include this load instruction before the instruction that sets MSR[EE].
