Interrupt Controller
7.2
The interrupt controller register portion of the SIM memory map is shown in
All external interrupt inputs are edge sensitive, with the active edge being programmable through PITR.
An interrupt must remain asserted for at least three consecutive rising edges of CPU_ExtCLK to be
considered valid. The priority level of each interrupt source is programmed through the ICRs.
The MCF5272 does not support auto-vectored interrupts. Interrupt service routines for all interrupts should
have vectors in the user-defined interrupt region of the vector table (vectors 64–255). The location of these
vectors is programmable through the PIVR. For more information on the servicing of interrupts, see
