Note: This diagram represents the ILBS behavior when IRQMUX[0:1] = 11
The IRQMUX bits determine how many levels of IMB3 interrupts are sampled. Refer to
12.4.4
The interrupt synchronizer latches the 32 levels of interrupts from the IMB3 bus into a register which can
be read by the CPU or other U-bus master. Since there are only eight lines for interrupts on the IMB3 and
32 levels of interrupts are possible, the 32 interrupt levels are multiplexed onto eight IMB3 interrupt lines.
Apart from latching these interrupts in the register (UIPEND), the interrupt synchronizer drives the
interrupts onto the U-bus, where they are latched by the interrupt controller in the USIU.
If IMB3 modules drive interrupts on any of the 24 levels (levels eight through 31), they will be latched in
UIPEND in the UIMB. If any of the register bits 7 to 31 are set, then bit 7 will be set as well.
