NOTES:
Make sure that the PORRESET does not carry any glitches. The MPC5200B has no filter to prevent them from getting into the
chip.
HRESET and SRESET must have a monotonous rise time.
The assertion of HRESET becomes active at Power on Reset without any SYS_XTAL clock.
For additional information, see the MPC5200B User Manual [1].
3.3.3.1
Reset Configuration Word
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 will be locked immediately with the
SYS_XTAL clock (see Figure 3).
