the power supplied to the PLL is filtered using a circuit similar to the one shown in following
effectiveness, the filter circuit is placed as closely as possible to the AV
as possible. The ground connection should be near the AV
followed by the 1-µF capacitor, and finally the 1 ohm resistor to the board supply plane. The capacitors are connected from

Note the following:

In all low power mode by default, all input and output pads remain driven as per normal functional operation. The inputs remain
enabled.
The exception is that in Deep Sleep mode, GCR[DEEPSLEEP_Z] can be used to tristate a subset of output pads, and disable
the receivers of input pads as defined in
for details.
3.4
Due to large address and data buses, and high operating frequencies, the device can generate transient power surges and high
frequency noise in its power supply, especially while driving large capacitive loads. This noise must be prevented from reaching
other components in the MPC8535E system, and the device itself requires a clean, tightly regulated source of power. Therefore,
it is recommended that the system designer place at least one decoupling capacitor at each V
and LV
GV
must be placed directly under the device using a standard escape pattern as much as possible. If some caps are to be placed
surrounding the part it should be routed with short and large trace to minimize the inductance.
