1.3.4.1
During reset (HRESET and PORRESET) the Reset Configuration Word is latched in the related Reset Configuration Word
Register with each rising edge of the SYS_XTAL signal. If both resets (HRESET and PORRESET) are inactive (high), the
contents of this register are locked immediately with the SYS_XTAL clock (see
1.3.5
The MPC5200B provides three different kinds of external interrupts:
The propagation of these three kinds of interrupts to the core is shown in the following graphic:

Four IRQ interrupts
Eight GPIO interrupts with simple interrupt capability (not available in power-down mode)
Eight WakeUp interrupts (special GPIO pins)

External Interrupts
Reset Configuration Word
PORRESET
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.
