Resets
The MPC5200B has three reset pins:
PORRESET—Power on Reset
HRESET—Hard Reset
SRESET—Software Reset
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 MPC5200B inputs, as specified in the DC Electrical Specifications section. Table 14
specifies the pulse widths of the Reset inputs.
For PORRESET the value of the minimum pulse width reflects the power on sequence. If PORRESET is asserted afterwards
its minimum pulse width equals the minimum given for HRESET related to the same reference clock.
The tVDD_stable describes the time which is needed to get all power supplies stable.
For tlock, refer to the Oscillator/PLL section of this specification for further details.
For tup_osc, refer to the Oscillator/PLL section of this specification for further details.
Following the deassertion of PORRESET, HRESET and SRESET remain low for 4096 reference clock cycles.
The deassertion of HRESET for at least the minimum pulse width forces the internal resets to be active for an additional 4096
clock cycles.
NOTE
As long as VDD is not stable the HRESET output is not stable.
NOTE
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.
