System Integration Module (SIM)
9.4.3
The MCF5253 supports four software interrupts. These interrupts are activated by writing a 1 to an
ExtraInt register bit. When active, the interrupts can generate a normal interrupt exception to the ColdFire
processor. The interrupt exception is only generated if the corresponding level register interrupt mask is
higher than the current processor interrupt mask.
9.4.4
To allow measuring interrupt latency during device debugging, two interrupt monitor pins INTMON1 and
INTMON2 are available. These pins can be programmed in the Extraint register to output on any of the 64
interrupts available on the secondary interrupt controller.
