5.1
5.1.1
The interrupt controller has the following features:
Interrupt priority registers (IPRs) for setting interrupt priorities
Interrupts other than NMI can be assigned to two priority levels on a module-by-module basis
in interrupt priority registers A and B (IPRA and IPRB).
Three-level masking by the I and UI bits in the CPU condition code register (CCR)
Independent vector addresses
All interrupts are independently vectored; the interrupt service routine does not have to
identify the interrupt source.
Seven external interrupt pins
NMI has the highest priority and is always accepted; either the rising or falling edge can be
selected. For each of IRQ
independently.
