17.12.5 Interrupt Control Section (ICS)
The interrupt control section delivers the interrupt level to the CPU. The interrupt control section adapts
the characteristics of the MIOB request bus to the characteristics of the interrupt structure of the IMB3.
When at least one of the flags is set on an enabled level, the ICS receives a signal from the corresponding
IRQ pending register. This signal is the result of a logical “OR” between all the bits of the IRQ pending
register.
The signal received from the IRQ pending register is associated with the interrupt level register within the
ICS. This level is coded on five bits in this register: three bits represent one of eight levels and the two
other represent the four time multiplex slots. According to this level, the ICS sets the correct IRQ[7:0] lines
with the correct ILBS[1:0] time multiplex lines on the peripheral bus. The CPU is then informed as to
which of the thirty-two interrupt levels is requested.
Based on the interrupt level requested, the software must determine which submodule requested the
interrupt. The software may use a find-first-one type of instruction to determine, in the concerned MIRSM,
which of the bits is set. The CPU can then serve the requested interrupt.
