Electrical and Thermal Characteristics
3.3.4
The MPC5200 provides three different kinds of external interrupts:
The propagation of these three kinds of interrupts to the core is shown in the following graphic:
Due to synchronization, prioritization, and mapping of external interrupt sources, the propagation of
external interrupts to the core processor is delayed by several IP_CLK clock cycles. The following table
specifies the interrupt latencies in IP_CLK cycles. The IP_CLK frequency is programmable in the Clock
Distribution Module (see Note

Beware of changing the values on the pins of the reset configuration word
after the deassertion of PORRESET. This may cause problems because it
may change the internal clock ratios and so extend the PLL locking process.
