Notes:
1) The frequency of IP_CLK depends on register settings in Clock Distribution Module. See the MPC5200 User Manual [1].
2) The interrupt latency descriptions in the table above are related to non competitive, non masked but enabled external
Since all external interrupt signals are synchronized into the internal processor bus clock domain, each of
these signals has to exceed a minimum pulse width of more than one IP_CLK cycle.
NOTES:
1) The frequency of the IP_CLK depends on the register settings in Clock Distribution Module. See the MPC5200 User Manual
2) If the same interrupt occurs a second time while its interrupt service routine has not cleared the former one, the second
Besides synchronization, prioritization, and mapping the latency of an external interrupt to the start of its
associated interrupt service routine also depends on the following conditions: To get a minimum interrupt
service response time, it is recommended to enable the instruction cache and set up the maximum core
clock, XL bus, and IP bus frequencies (depending on board design and programming). In addition, it is
advisable to execute an interrupt handler, which has been implemented in assembly code.
