Interrupt Control Unit (ICU)
Daisy Chain
The ICU is composed of 2 interrupt blocks with a daisy chain capability (transmitter and
receiver blocks). The daisy chain allows more than one circuit to be connected on the
same interrupt line. Figure 22 shows the use of a daisy chain. IRQxx, IACKxx, IEIxx,
IEOxx must be understood as generic signals. They are IRQTX, IACKTX, IEITX, IEOTX
for the transmitter block and IRQRX, IACKRX, IEIRX, IEORX for the receiver block.
If IEIxx = 0, no higher device have an interrupt pending on the same line so the interrupt
is requested and the IEOxx is forced high to disable lowest devices to generate inter-
rupt. If IEIxx = 1, it waits for the condition IEIxx = 0. When IEIxx is tied high, IEOxx is
forced high.
The daisy chains can be used to program a priority between receivers and transmitters
interrupts when only one interrupt level is needed. An example is given in “Microproces-
sor Interface” on page 33.
