Electrical and Thermal Characteristics
3.3.3
The MPC5200 has three reset pins:
These signals are asynchronous I/O signals and can be asserted at any time. The input side uses a Schmitt
trigger and requires the same input characteristics as other MPC5200 inputs, as specified in the DC
Electrical Specifications section.
Notes:
1. For PORRESET the value of the minimum pulse width reflects the power on sequence. If PORRESET is asserted afterwards

4. For t
5. Following the deassertion of PORRESET, HRESET and SRESET remain low for 4096 reference clock cycles.
6. The deassertion of HRESET for at least the minimum pulse width forces the internal resets to be active for an additional 4096

CAUTION—The SYS_XTAL_IN frequency and system PLL_CFG[0-6] settings must be chosen such that the
resulting system frequencies do not exceed their respective maximum or minimum operating frequencies. See the
